Quel est le matériau principal d'une batterie au lithium?

08/13/2021

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.

Expand data:

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 battery:

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
