What caused the cell phone battery explosion?

Source: 2020 - 03 - 25 thou hits: what causes the cell phone battery explosion? The battery really explode? Will. Battery as energy storage is part of the battery, but when overcharge, over discharge, it is possible to breakthrough in the rest of the battery diaphragm, make the battery short-circuit, constitute a burst of high temperature and high pressure. So mobile phone battery in the process of charging is most likely to burst. Under what circumstances will explode? In addition to charge blasting, the phone battery charging to also explodes. Reason is the mobile phone has already formed the high voltage before charging, reached the critical point of battery shell, when the ambient temperature and pressure exceeds the critical point, would explode. Mobile phone battery explosion, in short, there are three main reasons: 1. Batteries at present, the quality of the number of mobile phones have taken place in China caused by 'original battery explosion. Industry veteran said, these are counterfeit battery waste battery recycling, too many impurities, the original data process is unqualified, battery safety protection of the relevant design does not reach the designated position, will constitute a battery explosion. 2. The battery has been charged for a long time in the case of charging for a long time, charging and over current will cause high temperature and high pressure, of the danger. Lithium batteries in special conditions such as temperature, humidity and poor contact may instantly discharge and generate a large amount of electric current, the combustion or explosion. 3. Battery short circuit when the mobile phone is in high temperature, or hit, metal friction, battery could form a short circuit, an explosion. How to properly charge, blowout preventing cell phone? 1. Use high quality original batteries battery quality is still very important. Must choose original battery, prevent the use of fake, residual battery. Cell surface is often covered with a layer of safety film. When the battery pressure reaches a certain peak, safety film burst release pressure, protect cells from the blast. But shanzhai battery, remaining battery must have a safety film to protect the safety of the battery, first of all to hold the battery, the inside of the special special soft or hard is fake batteries. More expensive brand batteries and a few yuan of counterfeit batteries is not only the price difference. In addition, it is better to replace hard hit or battery with serious scratches. For all-in-one PC, Like the iPhone series) , don't consciously after testing machine in damp environment or into the water recharge, prevent for mobile phone explosion to form a short circuit. 2. Selects the high quality charger for lithium battery charging process is generally constant current, constant pressure again, the function of the original mobile phone chargers after full discharge, is to prevent excessive charging. Shanzhai, incomplete charger without this function. 3. Attention to cell phone charging battery temperature should be put in the direction of the ventilation, don't put the battery back on the ground, so as to avoid in the process of charging battery burst due to the high temperature. Second, when the use of mobile phones, especially when running large mobile games, must be moderate, don't let the phone temperature becomes too high. Don't charge their phone at low temperatures. In the low temperature is lower than 0 & deg; C, will be far below the normal charging fees, this will lead to incomplete equilibrium rate of positive and negative reactions could not be completed, leads to the formation of a residual deposits of lithium ions in crystals, lead to the diaphragm punctured, blasting, as a result of the battery internal short circuit. Don't put the battery in high temperature environment, do not stop the violent impact and kneading, prevent the cells exposed to the sun. 4. Found abnormal stop charging charging such as the abnormal found that mobile phone should be immediately shut down, don't use of cell phones immediately after shutdown. Deformations can occur if the battery or rise, don't use it.
