1. Mobile phone battery, high energy lithium battery. Bulge, expansion, please do not continue to use, so as to avoid dangerous situations, at this time, please replace the battery in time!
2. Mobile phone battery, the use of life, generally used for one to two years, there will be problems, problems are mainly due to improper use, battery factory, poor quality, imperfect structure caused by.
3. The metallic properties of lithium are doomed to occur when the bulge bursts into contact with oxygen in the air, which will oxidize and cause the risk of explosion.
4. In fact, the charge and discharge of lithium batteries, what happens is a chemical reaction, when charging, the lithium atom of the positive electrode of the lithium-ion battery will lose an electron when charging, and become negative as lithium ion. Lithium ions swim through lye to the negative electrode, and then storage, discharge process, conversely, release a lithium ion, reduced to lithium atoms. It is not durable because of internal consumption.
5. There is a layer of diaphragm paper inside the battery, and a good barrier paper can actively close the fine hole when the battery temperature is too high, so that lithium ions cannot cross and prevent damage. However, when the quality of diaphragm paper is not up to standard, it will cause harm.
