When the cell phone battery swells, the battery storage capacity decreases and it can no longer be used. Please replace the battery in time to avoid dangerous situations.
Mobile phone batteries are high-energy lithium batteries. If the battery swells or swells, it is due to overheating inside the lithium battery or the quality of the battery itself, making it unsafe to reuse.
When I usually charge my mobile phone, if I don't pay attention to it, I will find that the mobile phone will swell after a while. Successive cell phone battery explosions are also caused by not paying attention to battery usage and overcharging.
The lifespan of cell phone batteries usually causes problems after one to two years of use. The main problem is that it is used. is thatworn out by misuse, poor quality and imperfect structure when the battery leaves the factory.
Lithium is a metal. When the bulge is exposed to oxygen in the air, an oxidation reaction occurs, resulting in a risk of explosion. When charging and discharging lithium batteries, a chemical reaction occurs. The lithium ion battery is charged, the lithium atom in the positive electrode will lose an electron and become negative and become a lithium ion. The lithium ions swim to the negative electrode through the alkaline solution, then are stored and discharged. Rather, a lithium ion is released and reduced to lithium atoms. It is not sustainable due to internal consumption.
There is a layer of diaphragm paper inside the battery. A good diaphragm paper can automatically close the pores when the battery temperature is too high, preventing the passage ofs lithium ions and avoiding any damage. But when the quality of the separator paper is not up to standard, it can cause damage.
Lithium batteries contain electrolyte. After several redischarges, some of the electrolyte breaks down to produce gas, causing the battery to expand. Do not use heavily swollen lithium batteries.
Lithium batteries currently on the market are essentially made up of electrolytes configured with lithium hexafluorophosphate. They begin to decompose at high temperatures, react chemically with the solution and release gases such as carbon dioxide.
The development of new lithium salts for electrolytic solutions cannot be overcome at the moment. Try not to use it for a long time at high temperatures.
