Do you know why lithium-ion batteries explode?

1. The charger does not match the battery: Generally, mobile phones have original chargers. A charger of the wrong model is likely to cause a battery accident. Apple mobile phones only accept the original charger to charge, which greatly reduces the chance of battery explosion. 2. Charging causes the battery to explode: playing with the phone while charging, and charging while playing will cause the charging time to become longer, and charging for a long time will cause the temperature of the phone to rise, making it easier to explode. 3. Battery short circuit: When the mobile phone is in a high temperature state, or is subject to impact, metal friction, etc., it may cause the battery to short circuit and explode. 4. The battery is overcharged for a long time: In the long-term charging state, overcharge and overcurrent will also cause high temperature and high pressure, which may cause hidden dangers. Lithium-ion batteries may instantaneously discharge under special temperature, humidity, and poor contact conditions, resulting in a large amount of current, spontaneous combustion or explosion. 5. Thermal runaway: The reason why lithium-ion batteries may explode is due to a process called thermal runaway in the reaction inside the battery. Thermal runaway is a positive energy feedback cycle: increased temperature will cause the system to heat up, and the system will heat up and increase the temperature, which in turn makes the system hotter. The above reasons such as short-circuit of the battery, high ambient temperature, frequent overcharging, unauthorized modification of the casing, etc., will cause thermal runaway of the lithium-ion battery, which may eventually cause fire or explosion. 6. Excessive temperature: Excessive temperature means that the internal heat of the battery has reached, and long-term charging, high-temperature irradiation, and baking can easily cause the battery's temperature to be too high. In southern my country, ordinary households use electric ovens in winter. Many people like to use their mobile phones while grilling on the electric oven. This is also very dangerous and can easily cause battery explosions. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
