The high-performance thermal-aware sensors

South Korean researchers have successfully developed a high-performance thermal-aware sensors. The sensor can sense the current performance of the thermal sensor similar to increase by 100 times, and can effectively prevent the IBM ThinkPad T41 battery from exploding due to overheating.and it can allow conductive insulator.an insulator can be changed in a specific temperature conductors by using of this technique.

Jin Xianzhuo and others further developed out of a high-performance thermal-aware sensors. The sensor can be used with home appliances such as Ibm thinkpad r50p battery , and can prevent them from overheating when the blast. Experiments showed that explosion temperature what mobile phones use rechargeable lithium battery is 177 degrees Celsius, while we used high-performance thermal-aware sensor polymer lithium-ion battery, under high temperature at 210 degrees Celsius ,it can not cause an explosion. In addition, after using of high-performance thermal sensing sensor, the rechargeable lithium Ibm thinkpad r50 series battery can avoid significant expansion due to overheating.

High-performance heat can sense sensors 100 times than the existing similar one , in view of this characteristic, high-performance thermal-aware sensors can not only widely be used in food fermentation, fire alarm,Ibm thinkpad a30 battery and other areas, but is expected to be used in military, aviation the field of aerospace thermal sensing devices.

The Google smart phone battery

Rumors have been selected because of Google smart phone HP Pavilion ZV5000 battery supplier, China's laptop and cell phone battery manufacturers BAK Battery, Inc. is soaring with the stock on the Nasdaq Stock Market.

The hp pavilion dv4000 battery Company in Shenzhen, it is up to 63 percentage maximum to 3.63 U.S. dollars by the deadline to close up, since it is the company's highest since June 2004 gains.

Roth Capital Partners analyst Maketuobin, said in an interview in the "rumors which have been produced in Google was originally Ibm thinkpad r50e battery suppliers, if this is true, this is the perspective from the proceeds of which may only just begun."

China BAK Ibm thinkpad t42 battery , Inc. In recent years, laptop and cell phone battery supply is more than doubled in the Sussex China Index (US-listed Chinese companies base) to create a 62% rise.

Proper maintenance of lithium-ion battery

Although the lithium-ion latitude d600 battery has little memory effect than nickel-cadmium battery, memory effect of the principle is that crystallization, there will be little reaction in the lithium batteries. However, lithium-ion battery capacity will continue to decline after repeated charge-discharge, its causes are complex and diverse. Is mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ion on the hole to accommodate the structure will gradually collapse, plug; from the chemical point of view, is the active anode material is passive, there's the other side to form a stable compounds. Physics will appear on the cathode material gradually falling off, etc., in short, can ultimately reduce the Apple Battery charging and discharging process of the free movement of the number of lithium-ion.

Over-charging and over-discharge, lithium-ion latitude d820 battery will damage positive and negative permanently , from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium-ion and makes it appear lamellar structure collapsed, over - Rechargeable lithium-ion will too hard go into the negative carbon structure, causing some of the lithium-ion can no longer be released. This is why lithium-ion batteries are usually equipped with charge-discharge control circuit causes.

if the temperature is Not suitable, it will lead to producing the other chemical compounds that we do not want to see inside the lithium-ion latitude d830 battery , so many of the lithium-ion batteries are being set up between the protective negative temperature-controlled diaphragm or electrolyte additives. In the battery temperature to a certain case, the composite membrane electrolyte membrane hole closed or degeneration, increased battery internal resistance until the circuit, the battery is no longer to heat up, to ensure that the battery charging temperature is normal.

Our battery maintenance view is:

1. No need to ensure that every time a re-release END electric charge
2. A period of time to do a protection circuit placed under the control of deep-charge battery power to amend the statistics, but it does not improve the actual capacity of your vostro 1500 battery .
3. A long time without the battery, should be placed in the shade in order to weaken its internal self-passivation reaction speed.
4. Protection circuit is also able to monitor the battery self-discharge, long-term without the battery should be charging to a certain degree of power to prevent self-discharge of batteries in storage in the discharge of excessive lead to excessive damage. In fact, there is not much to take into account the battery use of attention, in other words is taken into account is not much use. The number of times a cell can use, and perhaps more from the xps m1330 battery itself, differences in the manufacture of individual differences, rather than use.
