NONAQUEOUS ELECTROLYTE BATTERY AND CHARGING METHOD THEREFOR

Title:

NONAQUEOUS ELECTROLYTE BATTERY AND CHARGING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/1998/040923

Kind Code:

A1

Abstract:

A nonaqueous electrolyte battery using titanium oxide or lithium titanate as a negative electrode material of a negative electrode, wherein a polymer electrolyte is provided between the negative electrode and a positive electrode. By thus using titanium oxide or lithium titanate as the negative electrode material of the negative electrode and providing the polymer electrolyte between the negative electrode and the positive electrode, the polymer electrolyte is less likely reduced and decomposed by a catalytic action of titanium oxide or lithium titanate, and lowering of charge and discharge efficiency as in the case where a nonaqueous electrolyte solution is used is restrained. Thus, a nonaqueous electrolyte battery having high charge and discharge efficiency is provided.
