Graphene Compound, Method for Forming Graphene Compound, and Power Storage Device

A method for forming a graphene compound, comprising steps of:

• stirring graphene oxide and a Lewis base to form a first mixed solution;
• mixing a silicon compound that comprises one or more ester groups or carboxyl groups into the first mixed solution and stirring the mixed solution to form a second mixed solution;
• and
• filtering the second mixed solution and collecting an obtained residue,
• wherein the residue comprises a graphene compound.

A method for forming a graphene compound, comprising steps of:

• stirring graphene oxide and butylamine to form a first mixed solution;
• mixing a silicon compound into the first mixed solution and stirring the mixed solution to form a second mixed solution;
• and
• filtering the second mixed solution and collecting an obtained residue,
• wherein the silicon compound is one of 11-acetoxyundecyltrichlorosilane, 2-acetoxyethyltrichlorosilane, and 2-(carbomethoxy)ethyltrichlorosilane, and
• wherein the residue comprises a graphene compound.
