摘要

Provided is an electrode material which is capable of providing an active material that has excellent water dispersibility and is also capable of providing an electrode that has excellent battery performance even in cases where the electrode material is used in the form of an aqueous slurry. Specifically disclosed is an electrode material containing an active material, which is characterized in that the active material has a structure coated with a conductive carbon material and the nitrogen atom content relative to 100% by mass of the total of the active electrode material is not less than 0.3% by mass.
