摘要： In the present method, a non-aqueous electrolyte secondary battery is charged by repeating n+1 times a constant current charge and a subsequent constant voltage charge, where n is an integer of 1 or more. (1) An nth charge comprises charging the secondary battery at a current Ic(n) to a voltage Ec(n), and subsequently charging the secondary battery at the voltage Ec(n) until the current decreases from Ic(n) to Ic(n+1). (2) An (n+1)th charge comprises charging the secondary battery at the current Ic(n+1) to a voltage Ec(n+1), and subsequently charging the secondary battery at the voltage Ec(n+1) until the current decreases from Ic(n+1) to Ic(n+2). Consequently, the charge time of the non-aqueous electrolyte secondary battery can be shortened while deterioration of the battery can be suppressed.

The sealing plate has an external terminal of the positive or negative electrode, and an internal terminal electrically connected to the positive or negative electrode. The external and internal terminals are connected to each other and have an electrical resistance therebetween of 0.1 to 2 mΩ. Two or more constant-current charging steps in each of which the secondary battery is charged at a constant charge current until a charge voltage reaches an end-of-charge voltage are performed. In the two or more constant-current charging steps, the secondary battery is subjected to constant-current charging at a current Ic(1) of 1 to 5 C until the charge voltage reaches a target voltage Ecs(1). After the charge voltage reached the target voltage Ecs(1), the secondary battery is subjected to constant-current charging at a current Ic(k) satisfying Ic(k)
