METHOD FOR RECYCLING SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method for reducing the number of useless secondary batteries when secondary batteries, which constitute a plurality of battery packs, collected from users or markets are assembled to reconstitute a new battery pack.

SOLUTION: Battery packs collected from the users or markets are recovered (S101) and disassembled to secondary batteries (S102); the characteristics such as full charge capacities of single cells are measured (S103); secondary batteries are classified by setting so that the tolerance of dispersion increases with decrease in full charge capacity (S104, S105); and a battery pack is reassembled with classified secondary batteries (S106).
