Why lithium battery need add PCB can use?
-The function of protection plate mainly to charging type battery-cells to protect,keeping battery charging and discharging process of security and stability,and the performance is very important for whole battery circuit system.(Generally lithium battery consist of cells,protection board and the shell,such as mobile phone)
Lithium polymer batteries whether it will explode or not?
Polymer li-ion battery due to use colloidal electrolyte(Al-Plastic package),and it won’t due to boiling liquid to come into being a lot of gas to explode, thus it was improved batteries safety.
Polymer battery and lithium battery which one more better?
Compared with general lithium batteries, polymer battery has high energy density, miniaturization, more thinner ,more lighter, high safety, long cycle life and low cost and so on, it will step by step instead of lithium batteries in the future.
