Electrolytic solution for regenerating power storage device, regenerated power storage device, and method for regenerating power storage device

摘要

An electrolyte solution for regeneration of an electricity storage device to be added after the discharge capacity has decreased by 1% or more with respect to the initial discharge capacity, characterized by having a higher electrolyte concentration and lower viscosity than the initial electrolyte solution. A regenerating electrolyte for an electricity storage device. According to the present invention, battery performance after replenishment can be appropriately improved.
