The role and types of lithium-ion battery

In the phone, whether it is from a technical point of assessment or from price considerations, the battery has played a very important position. Until now, mobile phones sold on the market, using the battery has been basically completed the transition from the nickel battery to lithium. Perhaps because the cell phone battery has just completed the revolution of the first nickel batteries to lithium, lithium is not uniform, in many cases not correct to say and practice is quite popular. Therefore, to understand a little knowledge of lithium batteries, to master the proper use of lithium is very necessary.

Types of lithium batteries
The secondary battery used in the market are mainly two types of nickel-metal hydride (Ni-MH) and lithium-ion (Li-ion). Liquid lithium-ion battery (LiB) and lithium-ion polymer battery (LiP) two lithium-ion battery production. Therefore, in many cases, marked on the battery of Li-ion, it must be the lithium ion battery. But is not necessarily liquid lithium-ion battery, there may be a polymer lithium ion battery.
The lithium-ion battery is a lithium battery improved products. Lithium long time ago, but lithium is a highly active (remember its position in the periodic table?) Of metal, it uses less secure, often in charge when burning, burst case, then there is an improved lithium-ion battery, adding the element lithium can inhibit active ingredients (such as cobalt, manganese, etc.) so that the lithium really achieve safe, efficient, convenient, and the old lithium battery will basically eliminated. As to how to distinguish them, able to identify from the label of the battery, lithium battery is Li, the lithium-ion battery is Li-ion. Now, notebook and mobile phone use so-called "lithium batteries", in fact, are lithium-ion battery.
The basic structure of modern batteries, including the three elements of the anode, cathode and electrolyte. As the battery is a lithium-ion batteries also have these three elements. Lithium-ion technology uses a liquid or inorganic gel electrolyte, and therefore needs a sturdy shell to accommodate the active ingredient combustible, which increases the weight and cost of the battery, also limits the flexibility of size and shape. In general, the minimum thickness of the liquid lithium ion secondary battery is 6mm, a further reduction is more difficult.

The so-called polymer lithium-ion battery is at least one or more of the three major tectonic polymer materials as their primary cell system. A new generation of lithium-ion polymer battery is already very high degree of the polymer of thin (0.5 mm thinnest), any area and arbitrary shape, greatly improved battery design flexibility, so the shape can be achieved , which can meet the demand for products made of any shape and capacity of the battery. The same time, the polymer lithium-ion battery, the unit of energy than current lithium-ion battery to improve the 50% capacity, charge and discharge characteristics, safety, operating temperature range, cycle life and environmental performance lithium-ion battery The magnitude of the improvement.

Currently marketed in the liquid lithium ion battery (LiB) in the case of overcharging, likely to cause safety valve rupture resulting in a fire situation, it is very dangerous, so necessary for the installation of the IC circuit protection to ensure that the battery will not occur over- charge of the case. Has good resistance to charge and discharge characteristics of polymer lithium-ion battery, the battery of this type of relatively liquid lithium-ion battery, external plus the protection of the IC circuit requirements can be relaxed. In addition to charging lithium-ion polymer battery can take advantage of IC constant current charging, the lithium ion secondary battery CCCV (Constant Currert-Constant Voltage) charge the manner required, you can shorten the wait time.

Application of mobile phone manufacturers of lithium batteries
Although in recent years almost all manufacturers have already tend to use lithium-ion battery, the world's major mobile phone manufacturers the choice of battery has its own characteristics and habits, for example, had the same historical period:
Nokia: the Ni-MH (nickel-metal hydride) battery, LiB (liquid lithium-ion) batteries, not LiP, (polymer lithium-ion) batteries.

Ericsson: Ni-MH batteries, battery LiB, LiP battery.
Motorola: Ni-MH battery, battery LiB not use LiP batteries.
Difficult to find, from the first choice of LiP polymer lithium-ion battery for mobile phones on this matter, Ericsson reflect the true nature of mobile phone technology pioneer. I find the data indicate that the main manufacturer of polymer lithium-ion battery for the Day * This SONY, Panasonic, GS, several companies, in 2000 the production volume reached 21 million, of which 50% for Ericsson mobile phones supporting. Enter 2002, lithium-ion battery in the other mobile phone manufacturers on the phone also has extensive application and popularization. However, the use of polymer lithium-ion battery, but also far not reached the degree of popularity, widely used in some time before all mobile phone manufacturers of the products.
On the other hand, although the advantages of lithium-ion battery, but there are defects, such as high prices and less charge and discharge times. Lithium battery charge and discharge times of only 400-600 times, specially modified products, but 800 times. Nickel-metal hydride battery charge cycles to reach more than 700 times, some good quality products to charge and discharge up to 1,200 times, so that a comparison of the nickel-metal hydride batteries than the lithium battery longevity. In addition, the price of nickel-metal hydride battery than the lithium batteries are much lower. Strictly speaking, the lithium battery is the same memory effect, but its memory effect is very low, basically negligible.
Hence, there is no perfect battery.

The use of lithium-ion battery
This is partly the focus of this article, we have three points to talk about.
1, for the new battery charge
Should be noted that the use of lithium, the battery into hibernation place for some time, and lower than normal capacity, the use of time has also come to shorten. However, lithium batteries can easily activated, the battery can be activated as long as 3-5 times the normal charge-discharge cycles back to normal capacity. Battery lithium own characteristics, it is almost no memory effect. The new lithium battery in the user's mobile phone during the activation process does not require special methods and equipment. Not only in theory, from my own practice, from the outset, the standard method of charging that "activation" is the best way.

For the lithium battery "activate" problem, many say: charging time must be over 12 hours, repeated three times, in order to activate the battery. This three times before charging to charge more than 12 hours "it is obvious from the nickel battery (such as nickel cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be the beginning of miscommunication. Lithium and nickel battery charge and discharge characteristics of a very big difference, and can tell you very clearly, I had access to all the serious official technical data emphasized that the charge and discharge lithium batteries, especially lithium liquid ion battery can cause great harm. Charge and therefore the best charge in accordance with the standard time and standard methods, particularly not more than 12 hours long charge. Typically, the statement introduced mobile phone charging method is suitable for the phone's standard charging method.
In addition, the lithium cell phone or charger after the battery is full will automatically stop charging, there is no electricity nickel charger for 10 hours "trickle" charge. In other words, if your lithium batteries in full, on the charger white filling. And we can not guarantee the battery charge and discharge protection circuit features and never change and quality foolproof, so your battery will be long in a dangerous brink. This is also another reason to charge against the chief.

In addition, for some on the phone, charging over a certain time, if they do not remove the charger system not only does not stop charging will begin to discharge - charge cycle. Perhaps the makers of this approach has its own purpose, but obviously in terms of the life of battery and cell phone / charger is unfavorable. Long charging takes a long time, often at night, while the situation of China's power grid voltage of the night in many places higher, but also volatile. Said earlier, the lithium battery is very delicate, it is much worse than the nickel electric resistance fluctuations in the charge and discharge capacity, so this brings additional risk.

In addition, another aspect can not be ignored is the lithium battery is also not suitable for over-discharge, over-discharge of lithium is also very unfavorable. This leads to the following questions.
2, in normal use should start charging
We often see this argument, because the charge and discharge cycles is limited, so you should phone the battery as much as possible run out of recharge. But I find that a lithium-ion battery charge and discharge cycle test table, the cycle life of the data is as follows:
Cycle life (10% DOD):> 1000

Cycle life (100% DOD):> 200 times
DOD is the abbreviation of the depth of discharge. Be seen from the table, the charge number and depth of discharge, 10% DOD cycle life than the 100% DOD for much longer. Of course, if equivalent to the relative total capacity of the actual charge: 10% * 1000 = 100,100% * 200 = 200, the latter complete charge and discharge, or better than some, but in front of friends do say that some correction: in the normal case, you should have a reservation in accordance with the principle of charging the remaining battery run out of charge, but if your battery when you expected to be two days can not persist throughout the day, you should start charging, of course, if you are willing to back charger to the office is a different matter.
You need to be charged to meet the anticipated upcoming busy communications event cause, even when the batteries are still a lot more than electricity, then you also just charge ahead, because you are not really lost a "charge cycle life , that is, "0.x" times, and often this x will be very small.
The remaining battery run out of charge of the principle does not want you to go to the extreme. And long, like charging widespread a statement, "as far as possible to the cell phone battery runs out, it is best to use automatic shutdown". This practice is only practice on nickel batteries, the purpose is to avoid the occurrence of memory effect, unfortunately, it also lithium spread today. It has been been used because the cell phone battery low warning appears, still do not charge to use the automatic shutdown of the examples. The results of this example, the mobile phone charging and starting later no response, had to give customer service overhaul. In fact, this is due to the battery due to excessive electrical discharges cause the voltage is too low, that does not have the normal charging and start-up conditions.
3, the correct practice of the lithium cell phone

To sum up, the issue of charging and discharging of the lithium cell phone in use is the most important tips are:
① charge its standard time and procedures, even before three have to do so;
② When the cell phone battery is too low prompt, it should be as much as possible in a timely manner to start charging;
(3) lithium battery activation does not require special methods will naturally activate the phone to normal use lithium. If you insist on spreading the three previous 12 hours long charge to activate "method, in fact, there will be no effect.
Therefore, all 12 hours long pursuit rechargeable lithium cell phone used in the automatic shutdown of the practice, they are wrong. If you ever do is the wrong argument, you correct them in time, perhaps not too late.

Of course, in the case of mobile phone and charger to protect themselves and control circuit of good quality, protection of lithium batteries or a considerable assurance. Understanding of the charging rules is the key, in some cases can make some concessions. For example, you find that the phone must be charged before you sleep at night, then you at bedtime to start charging. The crux of the problem, you should know what is the correct approach, and do not deliberately do the wrong argument.

The decomposition of the energy storage technolo

November 28, 2011, Taizhou, China new energy high-level forum to attract more than 200 guests attended around the country. China Strategic Capital Group Chairman Huang Yu Quan carries a vanadium battery report in the New Energy and Industrial Applications "on stage to do a wonderful speech. He said: new energy technology development has become the development trend of the global energy industry, energy storage technology has become the bottleneck of the new energy industry, the global venture capital last year, ranked first in the photovoltaic field, the second row in the storage area.

Energy storage technology is mainly divided into the physics of energy storage and electrochemical energy storage, in which the vanadium battery is the focus of attention.

"That change yesterday has changed today, and today will be the future of change". Huang Yu-quan firmly believe that the vanadium battery will change the future direction of the new energy industry, energy storage technologies.

Huang Yu the right to interview from Taizhou, and followed him from Taizhou went to Shanghai.
Why is urgent need to develop energy storage technologies?

Huang Yu-quan said, in the field of conventional energy, new energy technologies, mainly wind, solar, hydroelectric. New energy unlike ordinary thermal power generation, there are unpredictable and changeable characteristics, such as wind power: Due to the randomness of the wind, wind power directly to the Internet caused a great impact on the reliability of the grid, energy storage technologies and its industry is an increasingly important industry for wind, solar industry. In addition, the smart grid, through the allocation of storage of electricity to meet the peak demand for electricity, can increase the capacity of transmission and distribution systems and optimize efficiency.

The world by the Japan Nuclear spill, nuclear power has been a great misunderstanding of the environmental protection sector, before the elimination of security concerns, the new nuclear power will be very cautious, especially in the recent European cautious. It is due to the development of new energy storage technology can provide emergency backup power and remote island areas to solve power supply problems. Therefore, in all aspects of the entire power industry links, power generation, transmission, distribution and use of energy storage technology can be applied.

The benefits of energy storage technology should be applied in the power system which links the most appropriate, and to bring the power system is how much? Around the world in the most cutting-edge research is the U.S. Electric Power Research Institute, China's research in this area is relatively lag.
Huang Yu told reporters the right, the current mainstream energy storage technologies, including two types of energy storage and electrochemical energy storage of the physical class.

Physical class of storage: pumped storage, compressed air, flywheel energy storage and superconducting magnetic energy storage, open-cycle gas turbines and so on.
Electrochemical energy storage: sodium sulfur batteries, vanadium redox battery, lithium batteries.
Huang Yu-quan, and electrochemical energy storage technologies compared to other energy storage technologies are more obvious shortcomings: Pumped Storage by geographical limitations; compressed air long construction period, low efficiency; flywheels and superconducting magnetic energy storage technologies, storage time is short; open-cycle gas turbines, the funds have invested a large, low efficiency, large impact on the environment. In line with the development of clean energy direction in a variety of energy storage technologies is an electrochemical energy storage technology.

Electrochemical energy storage include: sodium sulfur batteries, vanadium batteries and lithium batteries, grid energy storage applications, in particular, wind power energy storage applications, vanadium battery and sodium sulfur batteries are the two major has been market-proven commercial technology. Existing global storage batteries, 90 percent of the megawatt-class projects are based on sodium sulfur battery. Close to 200 MW commercial scale in Japan, the sodium sulfur battery. The sodium sulfur battery charge and discharge a special control requirements, the need to increase the redundancy of 2-3 times. Lithium battery energy storage time is limited, and applies only to the grid frequency modulation. The best performing or vanadium battery battery capacity and duration.

Why the vanadium battery is in the direction of the energy storage technology?
Huang Yu-kuen, said the main advantages of the vanadium battery is the depth of the high current density discharge, long cycle life, rapid charge, the price relative to other energy storage devices is low, the vanadium battery is ideal for large static energy storage. The vanadium battery, the energy density is low, larger, from the large-scale energy storage applications, storage costs slightly higher price. Each energy storage technology has its advantages and disadvantages, so in the foreseeable future, the energy storage field are bound to exist the coexistence of sodium sulfur batteries, vanadium redox battery, lithium batteries and other technologies compete with each other does not exist in a technological monopoly the whole market situation.

The vanadium battery, the government level, with industry, and academia, there is consensus that the vanadium battery is best suited to China's development. First, China vanadium and mineral resources, with core technology through cross-border integration, Chinese companies have mastered the key technology of the world's vanadium battery, the characteristics of the vanadium battery is also suitable for the needs of the Chinese power grid, long life, reusable discharge, high reliability, can meet the needs of the Smart Grid.
Huang Yu-right that the full development and application of peaking storage batteries, will greatly enhance the operating efficiency of the power system. For example, he said, the national power generation equipment capacity in 2010 was 962.19 million kilowatts, of which thermal power was 706.63 million kilowatts, accounting for 73.4%; 213.4 million kilowatts of hydropower, accounting for 22.2%; 31.07 million kilowatts of wind power; 10.82 million kilowatts of nuclear power. Thermal power peaking capacity in the power generation, although our implementation of the TOU, but the difference between peak and valley generating capacity is still very large. Solve the power peaking is the subject of the world, the vanadium battery is a major revolution in energy storage technology, is expected to break through the bottleneck in the development of new energy industry.

"In recent years China has been increasing attention and policy support to the field of environmentally friendly low-carbon, in the foreseeable future, there will be more and more pure electric mode of transport, to say the least, even if the present market size, transport Power Battery is a huge market but we all know, the national concern about the environmental issues of lead-acid batteries since 2011, the Yangtze River Delta region already has shut down the size of more than 500 lead-acid battery manufacturers, according to the relevant departments planning, the 3000 lead-acid battery business to shut down the integration to the 300 lead-acid battery business, other small, do not meet environmental norms will be reorganization of mergers, these are directly placed in front of the battery industry and the electric car industry development bottlenecks. demand for these batteries is how to solve the capacity how to transfer, and are worthy of industry peers think about ". The face of the battery business development in China, Huang Yu-quan, "On the one hand may be lithium batteries to replace, but the forecast of the government agencies, lithium can replace lead-acid battery market share of 5-10%, even if you count the capacitor, the rest of most of or unfunded. lithium also stable security issues, while the lead-acid battery is the biggest problem is the issue of environmental protection ".

Huang Yu-quan delighted to tell reporters that the current solid-state electrolyte vanadium battery power in the electric power, charge and discharge, specific energy, and have been close to the level of lithium, lithium and lead-acid batteries in terms of safety, service life and cost a comparative advantage. China's annual output of lead-acid batteries 130 million KVAH January to June 2011 produced a total of 68 million KVAH. If 12V/120AH car battery, and an annual output of about 90 million. China's production accounts for 50 percent of the world. Global lead-acid battery is about $ 66 billion in sales in 2010.
And data estimates of the battery industry in recent years by China's "new energy automotive industry development plan, lead-acid batteries, electric car batteries, electric vehicle battery three total market of about 300 billion yuan. Energy storage devices, the market size of the large vanadium stack application of wind power energy storage devices, and the city peaking around 1.1 trillion. This is the country's economic development trend of the historic opportunity to bring to the vanadium battery industry.
Vanadium battery from Taizhou to the global.

China Strategic Capital Group is a large capital registered in Hong Kong Group, According to Huang Yu-quan, the investment involved in the field of iron and steel, nonferrous metals, nonmetallic, new energy and urban construction and development, the total investment in the mainland for more than 30 billion yuan, nearly a joint venture . Huang Yu said, the Taizhou will serve as the headquarters of the vanadium battery project, mainly for product integration and development ".

Huang Yu-quan, in Japan, for the rapid development of power plant peaking and wind energy storage of the vanadium battery, the power of the vanadium battery energy storage system has been put into use, and efforts to promote the commercialization process. However, in the country, the vanadium battery industry still in its infancy.
To this end, China Strategic Capital Group, introduced through the equity ties with Japan, South Korea vanadium battery technology, absorption, digestion and innovation, the formation of a joint R & D center in Japan and South Korea engineering and technical, and applied for a patent in over 150 countries around the world.

Huang Yu-Kuen China Strategic Capital Group, with extensive investment in the mineral field of energy, in Xuzhou, Nanyang established a production base of raw materials and the integration of wind, light, electricity storage in the nation's largest wind power base Yumen national demonstration bases. In addition, in Germany and South Korea were established production bases and R & D base of the vanadium battery.
Vanadium battery project in Taizhou, a total investment of $ 298 million U.S. dollars in accordance with plans, the project covers an area of ??1,800 acres, one of the project will be put into operation next year, when the formation of a $ 2.5 billion in sales are all put into operation in 2013. 10 billion yuan of industrial scale is expected to be formed, when the energy of ocean Thai the Zhongce Capital Group (Taizhou) Co., Ltd. will become the world's largest vanadium battery manufacturers in the production of vanadium batteries from Taizhou integrated Going Global ". Huang Yu-quan full of confidence, told reporters.

Youku and Tudou will be merged, so the advance p

Music Watch Copyright distributors to promote the significant increase in performance
Youku and Tudou merger when the A-share only video corporate music Watch (300 104) announced its 2011 earnings. Phase, Youku and Tudou total loss amounted to $ 108 million in performance, music Watch in 2011 achieved revenues of 598 million yuan, representing an increase of 151.22%; net profit of 131 million yuan, an increase of 87.05%, the results seem bright.

Unlike Youku and Tudou video companies rely on advertising revenue as the main source of revenue, music Watch are copyright to network video distribution for the main, the business accounts for about 60% of the total revenue, while the distribution of objects is the Fantastic Art, Youku, Sohu video and other video enterprises.

Copyright distribution revenue rose five-fold

Youku and Tudou to be merged so the advance publication of the Annual Report. Youku 2011 full-year net income of $ 142.6 million, representing an increase of 132 percent over 2010; Tudou last year revenue of approximately $ 81.4 million, an increase of 78.9%. But the two companies total loss of $ 108 million.

Music Watch the 2011 advertising revenue is only $ 1.14 billion, an increase of 69.90%, advertising revenue size and growth rate is obviously lower than Youku and potatoes. Music Watch in 2011 achieved total revenue of 598 million yuan, an increase of 151.22% over the same period last year; net profit of 131 million yuan, up 87.05 percent over the same period last year. The company intends every 10 shares of 9 shares and sent the cash dividend of 0.73 yuan (including tax).

Essence Securities analyst designate Lee pointed out that the benefit from the new media rights prices continued to rise and the company's initial investment in film and television content, copyrights, distribution become the main driving force of the company's revenue growth. 2011 copyright distribution of business income of 356 million yuan, an increase of 572%, total operating income ratio to 60%. As of December 31, 2011 Watch music has film rights to over 4000 television rights more than 70,000 sets, copyright authorization period of 3-7 years.

Report shows, music Watch the royalty income of 356 million yuan, more than half before the Fantastic Art, pptv, Youku, Sohu video and Thunder five video business, these five companies total 221 million pay TV royalties million. Copyright distribution of income will be the main source of the next two years, revenue, music Watch the expected first quarter net profit of about 5086.23 million yuan -5376.87 million, an increase of 75% -85%. It is reported that the company has obtained an exclusive network of more than 60% Copyright 2012 hit TV drama, the 2013 hit TV drama 40% -50% of the exclusive network copyright. Hou Lee pointed out, the future, although the rate of price increases will be lower than in 2011, yet the short term to see the turning point of less than prices.

Intends to transition the online video service providers

Although the copyright distribution allows the company to stand out in the video industry, but the music Watch intention to change the marketing strategy.

Watch music distribution changed to "cloud video platform for cooperation output to be adopted by the steady development of the next three years, before the purely copyright build open cloud video platform for enterprises or individuals to provide a" cloud video storage and distribution services, as well as PCs, mobile phones, the PAD and TV users of genuine high-definition video services, the development of China's largest online video service providers to form a "platform + content + terminal + application" business model.

To this end, the 2011 Lok Watch launched ultra-clear set-top boxes, and at the beginning of this year reached a strategic cooperation with CNTV (China Network Television) work together to explore the Internet set-top box market. Music Watch Internet TV audiovisual content and related products to provide CNTV CNTV broadcast control audit. Watch music content distribution resources cooperation projects will be the first to market in Shanghai, Hangzhou, Changsha and other places.

For the development of IPTV services, Minsheng Securities analyst Li Feng, ultra-clean machine business will be the Music Watch the new profit growth point, but the industry believes that ultra-clean machine pricing higher, and the need to rely on the the IPTV large-scale and business model matures thus the performance of ultra-clean machine, there is still much uncertainty in the short term music Watch will continue to rely on copyright distribution business.
