How to deal with cell phone battery bulge

by：Vglory 2021-03-25

Mobile phone batteries are high-energy lithium batteries. If there is bulging or swelling, please do not continue to use it to avoid dangerous situations. At this time, please replace the battery in time! The battery life of a mobile phone is generally used for one to two years, and then there will be problems. The problems are mainly caused by improper use in normal times, the quality of the battery is not good enough when it leaves the factory, and the structure is not perfect. Lithium’s metallic properties are destined to undergo an oxidation reaction when it is exposed to oxygen in the air when exposed to a bulge. It will oxidize and cause an explosion hazard. In fact, the charging and discharging of lithium-ion batteries is a chemical reaction. When charging, the lithium atom of the positive electrode of the lithium-ion battery will lose an electron and become negative and become lithium ions. Lithium ions swim to the negative electrode through the lye, and then are stored and discharged during the process. On the contrary, a lithium ion is released and reduced to lithium atoms. It is not durable because of internal consumption. There is a layer of diaphragm paper inside the battery. A good barrier paper can actively close the pores when the battery temperature is too high, so that lithium ions cannot pass through and prevent damage. But when the quality of the diaphragm paper is not good enough, there will be harm. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
