Advantages and disadvantages of polymer lithium ion battery

Advantages of polymer lithium ion battery

The shape of polymer lithium ion battery can be thin (at least 0.5 mm), arbitrary area and arbitrary shape, greatly improving the flexibility of battery design;

There is no excess electrolyte in the polymer lithium ion process, so it is more stable and has good environmental protection characteristics:

No leakage, heavy metal and pollution;

High energy density: 170~200Wh/Kg;

Large capacity single cell can be manufactured to avoid the impact of parallel connection (In China, no one can scale up the production of 2000mAh monomer for liquid cell, and the batch production of ATL polymer can reach 6000mAh monomer);

Excellent safety features: far superior to the traditional liquid lithium ion battery (there is no danger of explosion);

Disadvantages of polymer lithium ion battery

Due to the flexible packaging process of polymer lithium-ion battery, higher requirements are put forward for the processing requirements of the subsequent processes and the stability of the cell. It is easy to damage the cell due to the poor performance of the subsequent processes (mainly PCM welding and plastic case packaging), resulting in the cell inflation
