How to charge correctly to prevent the phone battery from exploding?

1. Choosing original batteries with excellent quality will explode. In the final analysis, it is a problem of battery quality. Be sure to choose original batteries to prevent the use of counterfeit or inferior batteries. The surface of the battery is usually covered with a safety film. When the battery pressure reaches a certain peak, the safety film will burst to release the pressure to protect the battery from explosion. However, counterfeit batteries and low-quality batteries may not have a safety film to protect the safety of the battery. When buying a battery, you must first pinch the battery. The inside is particularly soft or particularly hard. The price difference between the more expensive brand battery and the tens of yuan copycat battery is not only the price. In addition, it is best to replace a battery that has been hit by a hard object or has severe scratches. For all-in-one devices (such as the iPhone series) in a humid environment or after water has entered, do not blindly charge and test the device, lest it cause a short circuit and cause the phone to explode. 2. The charging process of choosing a high-quality charger for lithium-ion batteries is generally constant current and then constant voltage. The original mobile phone charger has the function of self-discharge after being fully charged, which is to prevent overcharging. Counterfeit and low-quality chargers do not have this function. 3. Pay attention to the battery temperature. When charging, the mobile phone should be placed in a ventilated place. Don't put the battery back down to prevent the battery from exploding due to high temperature during the charging process. Secondly, when using a mobile phone, especially when running large-scale mobile games, it must be moderate, and the temperature of the mobile phone should not become too high. Don't charge the phone in low temperature. In the low temperature state below 0 degrees, the charged power will be significantly lower than the normal power, which will lead to the insufficient balance rate of the positive and negative reactions, which will cause the excess lithium ions to form crystals and precipitate, causing the diaphragm to be pierced and causing the battery to internal A short circuit causes an explosion. Do not place the battery in a high-temperature environment, do not violently hit or squeeze it, and prevent the battery from being exposed to the sun. 4. Stop charging when an abnormality is found. If the mobile phone is found to be abnormal, it should be powered off immediately. Do not use the mobile phone immediately after the power is off. If the battery is deformed or swollen, do not use it again. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
