    • It is made possible to keep a nonaqueous electrolyte secondary battery in a charged state for a long period of time and minimize the degradation of the battery. A method for charging a nonaqueous electrolyte secondary battery including a cathode, an anode, and a nonaqueous electrolyte, includes: a first charging step of charging the nonaqueous electrolyte secondary battery at a first current value which increases the voltage of the nonaqueous electrolyte secondary battery; and a second charging step of charging the nonaqueous electrolyte secondary battery at a second current value which decreases the voltage of the nonaqueous electrolyte secondary battery. These two charging steps are repeated alternately.
    • 可以长期将非水电解质二次电池保持在充电状态,并使电池的劣化最小化。 一种包括阴极,阳极和非水电解质的非水电解质二次电池的充电方法包括:第一充电步骤,以提高非水电解质二次电池的电压的第一电流值对非水电解质二次电池进行充电; 以及第二充电步骤,以降低非水电解质二次电池的电压的第二电流值对非水电解质二次电池进行充电。 交替地重复这两个充电步骤。
