At present, most of the domestic polymer lithium-ion batteries are only pouch batteries, using aluminum-plastic film as the shell, but the electrolyte has not changed. This kind of battery can also be thinned, its low-temperature discharge characteristics are better than polymer batteries, and the energy density of the material is basically the same as that of liquid lithium-ion batteries and general polymer batteries, but because of the use of aluminum-plastic film, it is lighter than ordinary liquid lithium batteries. In terms of safety, when the liquid is just boiling, the aluminum-plastic film of the pouch battery will naturally bulge or break, and it will not explode.

1. When charging the polymer lithium-ion battery, it is best to choose the original special charger, otherwise it will affect or damage the polymer lithium-ion battery.

2. When charging polymer lithium-ion batteries, it is best to charge them slowly, and try to guard against fast charging, as repeated charging and discharging will also affect the life of polymer lithium-ion batteries.

3. If the mobile phone is not used for more than 7 days, the polymer lithium-ion battery should be fully used before use, and the polymer lithium-ion battery has self-discharge

4. The charging time of polymer lithium-ion battery is not as long as possible, for general chargers, when the polymer lithium-ion battery is overflowing, it should stop charging immediately, otherwise the polymer lithium-ion battery will affect the battery performance due to heating or overheating.

5. After the polymer lithium-ion battery is charged, try to leave it on the charger for more than 10 hours, and if it is not used for a long time, the mobile phone and the polymer lithium-ion battery should be separated.
