Lithium metal or lithium alloys and non-aqueous electrolyte solutions. Lithium batteries can be roughly divided into two categories: lithium-metal batteries and lithium-ion batteries.
Lithium metal battery:
Lithium metal batteries are generally batteries using manganese dioxide as cathode material, lithium metal or its alloy metal as cathode material, and that use non-aqueous electrolyte solution.
Discharge reaction: Li + MnO2=LiMnO2
Lithium-ion batteries generally use lithium alloy metal oxide as cathode material, graphite as cathode material, and use non-aqueous electrolyte batteries.
The reaction occurring on the charging positive electrode is LiCoO2==Li (1-x) CoO2 + XLi + + Xe- (electronic)
The reaction occurring on the charging negative electrode is 6C+XLi++Xe- = LixC6
Total reaction of charging battery: LiCoO2 + 6C = Li (1-x) CoO2 + LixC6
