Cell structure and classification:
I come to you now about the battery: the battery is a chemical energy directly into electrical energy. It can be divided into rechargeable batteries and non-rechargeable batteries. Now we have to look at the structure of non-rechargeable batteries, mainly divided into three levels: First, the outermost layer of "skin" is what we call the shell, for reactive chemicals, shell wrap middle graphite electrode. When the reaction of the chemicals into electrical energy to the external circuit to form a loop to create a current output from the graphite electrode: the HP COMPAQ NC8000 battery is working. Non-rechargeable batteries are divided into: the nickel-metal hydride batteries, nickel-cadmium batteries.
Second, the hazards of the waste batteries:
When the battery internal chemical reaction is complete, the 6910p Hp Compaq battery can no longer supply the became a scrap batteries, people usually readily lost, and then bought a new alternative. Most people would say this is normal Mile. But they did not expect that, under that gestures, but also in the destruction of their home - the earth. Some people may ask: "on such a small thing, to the earth, to have what is so amazing! Said any damage?" Battery looks not so destructive, but can not all see things at face value. Contains large amounts of heavy metals like mercury, cadmium, manganese, lead, waste Hp Compaq 8510p batteries. When the surface of the cortex of the sun and the rain of waste batteries corroded, one of the ingredients will penetrate into the soil and groundwater, once people eating contaminated land to produce crops or drinking contaminated water, toxic heavy metals enters human body, slowly deposited, causing a great threat to human health! It is measuring a NIKON EN-EL10 battery rotten No. 1 in the soil, so that one square meter of land lost value; a buckle button battery can contaminate 600,000 liters of water, the equivalent of a person's life, the amount of drinking water. 50 million people around the world to the nearest meter month per person throw a TOSHIBA PA3817U-1BRS battery, the cumulative 60 billion batteries a year, and the destructive power of the earth can be said that a lot of the more difficult to imagine the consequences on human health hazards , according to statistics, only Beijing each year due to waste NOKIA 6085 battery into the natural environment of the mercury has reached 29.6 tons, and this number can not help but headaches. Used batteries can not be thrown away. Countries attach great importance in battery recycling. In addition, the developed countries to produce sub-types of zinc-manganese battery is mercury-free batteries. Moreover, the developed countries are not allowed to be imported mercury Aspire 5315 Acer battery. Mercury batteries can not enter the developed regions of Europe and the United States.
Third, the processing of waste batteries:
Disposal of Hp Mini 110 Laptop external batteries can also start from the structure of the battery, first the surface of the skin, its main ingredient is zinc. In the three days of the experiment in this experiment:
1, waste Satellite A200 battery zinc leather take zinc sulfate crystals.
Experimental supplies: beaker, iron sets (with hoops), alcohol lamp, evaporating dish.
Dilute sulfuric acid, dry cell zinc skin.
Experimental procedure:
⑴, dry cell zinc skin surface impurities removed, put them in a beaker.
⑵, beaker pour the right amount of dilute sulfuric acid immersion zinc skin for the degree to be zinc skin dissolved.
(3), after the reaction solution was filtered.
⑷, the filtrate was poured into the evaporating dish, evaporating dish on hoops of iron sets, with an alcohol burner. Subject to an evaporating dish precipitated more crystal heating was stopped, the waste heat of the evaporating dish, and the filtrate was evaporated to dryness, the recovery of the zinc sulfate crystals, and put it into a specified container.
2, the second layer of the chemical substances in the composition is very complex and only advanced machines to extract the relevant component, and then made something useful. Japan has also been a plant, TOSHIBA PA3819U-1BRS battery recycling, extract the mercury, but a ton of waste batteries can extract up to several tens of kilograms of mercury, the factory last investment, the recovery of small and bankruptcy. Although the Government to encourage the development of this Industry, but many manufacturers did not dare to put their lives at risk. The innermost layer is of course the graphite electrode friends.
3, the Satellite M200 Toshiba battery of the innermost is graphite carbon rod, which also has a significant role, recovered with great economic value. Cut from the graphite under some powder touch the creamy feel. Graphite of this nature, it can be used as a lubricant. Some machines work at high temperatures with graphite powder as a lubricant, and addition to the application of the lubricating properties of the graphite powder, also applied to its high melting point, can be the nature of the high temperature. In fact, the graphite, there is another important use, is used to the manufacture of synthetic diamond, perhaps few people know graphite and diamond single mass is constituted by the carbon element, but a different order of their atomic arrangement, result in large differences between them graphite heating to 20000C, pressurized to 5 × 109 Pa ~ 1 × 1010 Pa and the presence of a catalyst under conditions that can create that shiny synthetic diamond. People saw the beauty of the diamond, and how they never think of it is made from graphite ink tetrahedrite, tetrahedrite.
Germany Kesi Ma Ms. working in China for nearly 20 years, she and her friends put waste Satellite L500D batteries back to Germany treatment, she only bought rechargeable batteries and mercury-free batteries in China. The Henan Xinxiang The Tian Guirong year to work tirelessly to promote environmental awareness spontaneously. Printed materials, engage in speech, invested tens of thousands of dollars to buy 30 tons of waste batteries. It seems that we should learn from them, to do their obligations. So, recycling and disposal of used batteries, not only to reduce its pollution of the environment and harm to human, but also brought us good economic benefits.
