Claim 4:
5. A method for manufacturing a storage battery electrode, comprising the steps of:
dispersing graphene oxide into a solution, the solution containing alcohol;
heating the graphene oxide in the solution so that an alkyl group is supported by an ether bond in the graphene oxide;
vaporizing a solvent in the solution at a temperature higher than or equal to 60° C. and lower than or equal to 170° C. after heating the graphene oxide; and
forming graphene by reducing the graphene oxide after vaporizing the solvent,
wherein the reducing the graphene oxide is performed by heating the graphene oxide at a temperature higher than or equal to 60° C. and lower than or equal to 170° C.
