NON-AQUEOUS ELECTROLYTIC SOLUTION, CELL PACK, AND METHOD FOR MANUFACTURING CELL PACK

WIPO Patent Application WO/2021/241762

A1

Provided is a high-capacity cell pack in which cell balance deviation is eliminated, precipitation of a sparingly soluble redox shuttle agent is prevented, overcharge-induced deterioration is suppressed, cell yield is improved, and a charge/discharge cycle is stable. The cell pack according to the present invention comprises a non-aqueous secondary battery including a non-aqueous electrolytic solution including an electrolyte salt and a non-aqueous solvent, a positive electrode and a negative electrode, the cell pack being characterized by including a module in which two or more non-aqueous secondary batteries are connected in series or being configured by connecting two or more such modules in parallel, or by being configured by connecting in series two or more modules each having two or more non-aqueous secondary batteries connected in parallel, the ratio of a maximum capacity (B) to a minimum capacity (A) of each non-aqueous secondary battery constituting the module being 1.00 < B/A < 2.00, and the non-aqueous electrolyte solution including a redox shuttle agent having a reversible redox potential at nobler potential than a positive electrode potential at a full charge time.
