Currently, most polymer lithium-ion batteries in China are simply pouch cells, using an aluminum-plastic film as the outer casing, but the electrolyte remains unchanged. These batteries can also be made thinner, and their low-temperature discharge characteristics are better than polymer batteries. Their material energy density is basically the same as liquid lithium-ion batteries and ordinary polymer batteries, but because they use an aluminum-plastic film, they are lighter than ordinary liquid lithium batteries. In terms of safety, when the liquid just boils, the aluminum-plastic film of the pouch battery will naturally bulge or rupture, and it will not explode.
1. When charging polymer lithium-ion batteries, it is best to use the original manufacturer's dedicated charger; otherwise, it may affect or damage the polymer lithium-ion battery.
2. When charging polymer lithium-ion batteries, it is best to use slow charging and avoid fast charging as much as possible. Repeated charging and discharging will also affect the lifespan 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 charged before use, as polymer lithium-ion batteries have a self-discharge phenomenon.
4. Longer charging time is not necessarily better for polymer lithium-ion batteries. For ordinary chargers, charging should be stopped immediately after the polymer lithium-ion battery is fully charged. Otherwise, the polymer lithium-ion battery will affect its performance due to heat generation or overheating.
5. After the polymer lithium-ion battery is fully charged, try to avoid leaving it on the charger for more than 10 hours. If the phone will not be used for a long time, it should be separated from the polymer lithium-ion battery.
