Battery Encyclopedia/Prismatic Li-polymer Battery VS Cylindrical Lithium Ion Battery

The distinction of square li-polymer battery and cylindrical lithium ion battery

1.The electrolyte of li-polymer battery is colloid and solid while lithium ion battery is liquid.

2.Li-polymer battery is flexible packaging and easy to deformation. Lithium ion battery is steel shell which is not easy to deformation.

3.Li-polymer battery is easy to become gas expansion, and then can’t use anymore. Lithium ion battery won’t happen to gas expansion.

4.In the same condition of volume, the capacity of li-polymer battery is bigger than lithium ion battery.

5.Li-polymer battery is hard to match group, while lithium ion battery is easy to match group. The cycle life of battery will be reduced greatly with bad group.

6.In terms of the safe performance of single cell, li-polymer battery is almost the same with lithium ion battery, but li-polymer battery is slightly better than lithium ion battery. As for battery pack, the safe performance of lithium ion battery is better than li-polymer battery.

7.As for installation and usage, lithium ion battery is far superior to li-polymer battery.

8.As for unit price, li-polymer battery is higher than lithium ion battery.

9.As for cycle life, lithium ion battery is longer than li-polymer battery.

10.All in all, the cost performance of lithium ion battery is higher than li-polymer battery.

Deformation and gas expansion example
