NONAQUEOUS ELECTROLYTE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery that offers excellent high-current output characteristics when the SOC is low.

SOLUTION: The nonaqueous electrolyte battery includes a positive electrode 3 including a positive electrode active material layer that contains a positive electrode active material containing a lithium-manganese complex oxide, and a positive electrode collector on which the positive electrode active material layer is formed; a negative electrode 4 containing a negative electrode active material that undergoes a charge-discharge reaction at a potential of 1 V or higher relative to lithium; a solvent containing diethyl carbonate; and a nonaqueous electrolyte containing LiPF6and LiBF4dissolved in the solvent. The molarity of LiPF6is higher than the molarity of LiBF4.
