Lithium-ion battery including a lithium-rich cathode and a graphite-based anode

摘要

An object of the present invention is a lithium ion battery including a graphite-based material for a negative electrode, a lithium-excess material for a positive electrode, an electrolyte, and a separator, wherein the reversible capacity (N) of the negative electrode is the reversible capacity of the positive electrode. It is a lithium ion battery with a capacity (P) equal so that the battery exhibits a ratio N / P = 1. The subject of the invention is also a method for producing a Li-ion battery according to the invention. Finally, the subject of the present invention is a method for cycling a lithium ion battery according to the present invention. [Selection] Figure 1
