Abstract
Irreversible capacity which causes a decrease in the charge and discharge capacity of a power storage device is reduced, and electrochemical decomposition of an electrolyte solution and the like on a surface of an electrode is inhibited. Further, the cycle characteristics of the power storage device is improved by reducing or inhibiting a decomposition reaction of the electrolyte solution and the like occurring as a side reaction in repeated charging and discharging of the power storage device. A power storage device electrode includes a current collector and an active material layer that is over the current collector and includes a binder and an active material. A coating film is provided on at least part of a surface of the active material. The coating film is spongy.
