Abstract

See full text

Provided is an electrode which gives an electric storage device that has high energy density and good cycle life. This electrode for an electric storage device is characterized by having an active material layer that contains: an electrode active material particle; and a paste-like conductive carbon that is derived from an oxidized carbon obtained by giving an oxidizing treatment to a carbon raw material with an inner vacancy and covers a surface of the electrode active material particle. The paste-like conductive carbon derived from the oxidized carbon is densely filled not only into a gap that is formed between the electrode active material particles adjacent to each other but also into a pore that exists on the surface of the active material particle, so that the electrode density is increased, thereby improving the energy density of the electric storage device. In addition, since the paste-like conductive carbon suppresses dissolution of the active material, the cycle characteristics of the electric storage device are improved.
