Reasons for looking for mobile phone explosion

In recent times, there have been a lot of reports on mobile phone battery explosion, which also caused public attention and uneasiness. So why is the mobile phone exploded? How big is it possible? How do I avoid this situation? Compared with other battery technology, the lithium-ion battery is lighter, cheaper, and more energy density is also higher. It has become the main form of rechargeable batteries, from all items from mobile phone to laptops in the use of lithium ion batteries.

But this battery has a problem, in some extreme cases, it may fire explosion. The reason why the lithium-ion battery will have an explosion, which is a disaster that is called "thermal out-control" process. In essence, "thermal out-of control" is an energy positive feedback cycle process: elevated temperature can cause system heat transfer, system heat rise, this is over, letting the system becomes hotter.

There are many reasons for thermal out of control of lithium-ion batteries. For example, when both ends of a lithium battery are connected, the tear of the membrane of the isolation of the lithium-ion battery negative electrode and the positive electrode will cause short circuit, and the short circuit tends to cause heat crash. The reasons for lithium-ion batteries also include: the ambient temperature exceeds 60 ¡ã C, often overcharge, physical damage, etc.

Regardless of the reason, experience this reaction is the cobalt oxide chemistry in the battery. If you heat this chemical, reach a certain temperature, it starts to heat up, then develop into a fire and explosion. Compared with the early lithium battery, now the lithium battery has repeatedly improved and perfect, in the performance of safety performance, as long as we ensure the correct operation in normal environments when we ensure everyday use, So the possibility of problems with lithium batteries is minimal.

Lithium ions are not long, usually two to three years (no matter if you use it). Therefore, all lithium-ion battery packs should be replaced once every 36 months; pay attention to avoid physical damage to the lithium battery, because physical damage may result in short circuit inside the battery; when the battery is stored separately, insulation should be performed. To ensure that the metal contact end of the battery is kept from any metal, such as a key, etc.

, you can use a relatively common sealing plastic bag to place the battery; the ambient temperature is too low or too high, which will cause permanent damage to the lithium battery, so it should be avoided to avoid harsh temperatures. Lithium battery in the environment. It should also be avoided by rain, water immersion, so as not to cause short circuits; although most digital products, their internal charging circuits are equipped with corresponding protection measures to avoid excessive charging of lithium batteries, but for insurance, we Still should avoid connecting lithium batteries for a long time and charger.
