What is the electrochemical principle of lithium ion battery?
The main composition of the positive electrode of lithium-ion battery is LiCoO2, and the negative electrode is mainly C,
Cathode reaction: LiCoO2 → Li1-xCoO2 + XLI + + Xe-
Negative reaction: C + XLI + + XE - → Clix
Total reaction: LiCoO2 + C → Li1-xCoO2 + Clix
The reverse reaction of the above reaction occurs during discharge.
