<p>PROBLEM TO BE SOLVED: To provide a graphene oxide with sufficient dispersibility in solvent, wherein graphene obtained by reducing the graphene oxide has a high electrical conduction property.SOLUTION: This invention provides a graphene oxide in which the ratio between carbon atoms and oxygen atoms (C/O) in X-ray photoelectron spectral analysis is 2.5 or more and 4 or less. The graphene oxide has moderate dispersibility in solvent, and graphene obtained by reducing the graphene oxide has a high electric conductivity and is suitable as an auxiliary conductive agent used for an active material layer of a secondary battery.</p> |
