Patent ID: 8922171

Claim:
A nonaqueous electrolyte secondary battery apparatus comprising a cathode, an anode, and a nonaqueous electrolytic solution comprising a nonaqueous electrolyte, a cathode terminal being connected to the cathode, an anode terminal being connected to the anode, the cathode terminal and the anode terminal being attached to a battery container via insulating components, wherein a first charging circuit providing a function to apply a voltage to the cathode terminal and the anode terminal is connected to the cathode terminal and the anode terminal, and a second charging circuit providing a function to apply a voltage to the battery container and the anode terminal is connected to the battery container and the anode terminal, and wherein the nonaqueous electrolytic solution comprises a sacrificial reducing agent, and the second charging circuit enables a voltage equal to or greater than a voltage at which the sacrificial reducing agent is oxidized on the battery container to be applied to between the anode and the battery container.
