Abstract
(A) A first lithium-ion battery is prepared. (B) A capacity loss of the first lithium-ion battery is detected. (C) Capacity restoration treatment is performed on the first lithium-ion battery having a detected capacity loss to produce a second lithium-ion battery. The first lithium-ion battery includes at least a positive electrode, a negative electrode, and an electrolyte solution. The electrolyte solution contains a lithium salt, a solvent, and an additive in advance of the detecting a capacity loss. The additive has an oxidation potential. The oxidation potential is higher than an OCP of the positive electrode in the first lithium-ion battery having a state of charge of 100%. The capacity restoration treatment involves charging the first lithium-ion battery in such a way that at least part of the additive is oxidized.
