1. Frequent deep charging and discharging: Lithium ion batteries have almost no memory. Many friends like to use the battery to the limit (protected by a protective plate) before recharging when using lithium trams or lithium digital products. In many people's eyes, this is also a way to activate the battery. In the use of lithium ion batteries, we call recharging after running out of power deep charging and discharging.

In fact, deep charging and discharging is a major mistake many people make when using lithium ion batteries. Scientists have concluded through experiments that the number of deep charging and discharging is proportional to the battery life when other environmental conditions are constant, and multiple charging and discharging will lead to the premature end of the battery life. However, the lithium-ion battery with a long service life is very easy to cause the battery bulge, which will lead to explosion.

2. Overcharging and discharging as well as excessive charging and discharging current: This often happens when the protective plate is designed unreasonably and charged. We often like to charge the device for a while after the device is fully charged, so that the device can withstand longer. However, many people cannot understand that long-term overcharge

So it's good that the battery is fully charged. If you plug it into the charger all the time, it will lead to tragedy sooner or later. At the same time, when charging and discharging, we also need the current of the charger and the general current load of the electrical appliance. Too high current load is very easy to cause internal short circuit of the battery, thus damaging lithium ions and causing potential safety hazards in the circuit. Similarly, the truth is the same with respect to the charging charger voltage. Therefore, when using the charger, we should also pay attention to whether the charger is qualified. However, after many accidents, the manufacturers finally took action, adding protective devices for most manufacturers, especially double protection or multiple protection for electronic and digital products, to prevent this situation as much as possible. However, it is still important to strengthen users' awareness. Lithium ion battery is extremely sensitive to temperature. If it is used below freezing point for a long time, it may cause great impact and harm to battery life. However, if the battery is placed in an overheated environment for a long time, its life will be greatly reduced. In serious cases, the increase of internal pressure will cause an explosion. Even if there is no explosion, the battery will be quickly scrapped in high heat. I feel that in some cases, the unfortunate death is caused by the pool explosion, most of which is caused by the high temperature of its working environment.
