Far away from the charging mobile phone

Compared with other reusable battery technology, lithium-ion battery is lighter, cheaper, and higher energy density. It has become now the main form of rechargeable batteries, especially in the application on the moviles android smart phone. Recently, we often hear the charge the phone battery explosion news. Therefore, I would like to explore some phone charging.
Reason why the lithium-ion battery will explode because of thermal runaway, essentially, "thermal runaway" is a the energy positive feedback cycle: elevated temperature elevated temperatures cause the system heats up, the system heats up, which in turn letting the system becomes hotter. Thermal runaway is a very common phenomenon, from the concrete curing (heat) will release a large number of physical and chemical processes of stellar explosion (supernova is a product of cosmic thermal runaway), are likely to appear thermal runaway. But inside the battery compartment of the phone, it can be a miniature bomb. If we use cheap batteries or does not comply with the standard battery of the phone, which is a safety hazard for us.
Although this uncontrollable reaction does not happen often, but the base number of the lithium-ion battery is too large, we feel that such incidents often occur. For example, in 2006, almost all the major laptop manufacturers - Apple, Hewlett-Packard, Toshiba, Lenovo, Dell and other companies - have received a report of a small amount of battery overheating condition recall products. Single apple a 9 report in the recall of 1.8 million units PowerBook and iBook. More importantly, the number of the battery size, configuration and the battery cell will affect the intensity of thermal runaway. Small battery pack (such as digital SLR cameras) are only a few battery power, thermal runaway propagation from the battery unit to the other unit is relatively low. And 787 huge battery pack is another matter: they are packed in sealed metal box, which can not be discharged waste heat, the result is that when a battery unit hot enough to ignite the electrolyte, and the rest of the battery unit will quickly with into.
However, the higher risk of mobile phone battery explosion, it once explosion likely to hurt your face and hands, and if you phone in your pants pocket inside, it can even lead to permanent damage of your sexual function.
So, whether you use a comprar moviles baratos or high-end mobile phones , you should develop a good habit of carrying. The best phone just put in separate parcels. Avoid be placed directly in the pockets of the clothes. The process of charging the phone, the phone is not to be placed at the bedside, At the same time, when the mobile phone charging, you'd better not let it leave you achieve. Once the result of the explosion caused a house on fire, you will likely have nothing.
