COMPOSITE BODY, METHOD OF MANUFACTURING COMPOSITE BODY, ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTE BATTERY AND NONAQUEOUS ELECTROLYTE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a composite body that can implement a nonaqueous electrolyte battery capable of having a high capacity maintenance efficiency.SOLUTION: A composite body 10 contains plural active material particles 12 of titan composite oxide or titan oxide and a graphene structure containing plural carbon materials 11b. Each of the graphene materials 11b has a graphene skeleton defining a graphene face 11c. The graphene structure 11 is located between the active material particles 12. The graphene structure 11 has at least one side surface 11a which is in contact with the active material particle 12. The side surface 11a contains the carbon material 11b in which the graphene face 11c is inclined with respect to the side surface 11a.
