Brief analysis of the eight advantages of polymer lithium-ion batteries
Jul 23 , 2021
Brief analysis of the eight advantages of polymer lithium-ion batteries 1. Good safety performance The structure of the polymer lithium-ion battery is aluminum-plastic soft packaging, which is different from the liquid battery with a metal shell. Once a safety hazard occurs, the liquid battery is easy to explode, while the polymer battery can only be inflated. 2. Lightweight Polymer batteries are ...

Why use protective plates for lithium iron phosphate battery packs?
Jul 29 , 2021
The protection of lithium iron phosphate batteries is determined by its own characteristics. Because the material of the lithium-ion battery itself determines that it cannot be overcharged, over-discharged, over-current, short-circuited, and ultra-high temperature charging and discharging, the lithium-ion battery package will always appear with an exquisite protection board and a current fuse. The...
