Working Principle Of Lithium Batteries

Lithium metal batteries:
Lithium metal batteries generally use manganese dioxide as the positive electrode material, metal lithium or its alloy metal as the negative electrode material, and use non aqueous electrolyte solutions.
Discharge reaction: Li+MnO2=LiMnO2
Lithium ion batteries:
Lithium ion batteries generally use lithium alloy metal oxides as the positive electrode material, graphite as the negative electrode material, and non aqueous electrolytes.
The reaction that occurs on the charging positive electrode is
LiCoO2=Li (1-x) CoO2+xLi++xe - (electronic)
The reaction that occurs on the charging negative electrode is
6C+xLi++xe -=LixC6
Total reaction of rechargeable battery: LiCoO2+6C=Li (1-x) CoO2+LixC6
