Lithium ion Polymer (Lipo) Batteries are employed with polymer electrolyte and is packed with Al laminated film. Li-polymer batteries offer several advantages. It has a great energy density in terms of weight. Additionally, there is more flexibility in cell sizes and shape with Lipo battery and a wider margin of safety, with superior stability in over-voltage and high temperature conditions.

Principle and Reactions:

When a lithium-based cell is discharging, the lithium is extracted from the anode and inserted into the cathode. When the cell is charging, the reverse occurs.

Positive reaction: LiCoO2 → Li1-xCoO2 + xLi+ + xe−

Negative reaction: xLi+ + xe− + 6C → LixC6

Total reaction: LiCoO2 + 6C → Li1-xCoO2 + LixC6
