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. |
