SEKUNDAERZELLE MIT NICHTWAESSRIGEM ELEKTROLYTEN.

摘要

A nonaqueous electrolyte secondary battery is disclosed, which comprises an anode having a carbonaceous material as the anode active material which permits lithium to be doped and undoped and a current collector, a cathode having a lithium compound as the cathode active material which permits lithium to be doped and undoped, and a nonaqueous electrolyte. The cathode active material contains the primary active material of a first lithium compound having the potential which is more "noble" than the potential of the current collector and the auxiliary active material of a second lithium compound having the potential which is more "base" than the potential of the current collector. The auxiliary active material works to avoid the dissolution of the anode current collector at the final stage of discharge.
