Method for modifying two-dimensional laminated and pleated graphene oxide material and application thereof to energy storage system having excellent physical/chemical properties and improved thermal properties, mechanical strength and electrochemical properties

This invention provides a preparation method of a pleated graphene oxide material, which is used as an active substance or additive to form a composite material applicable to an energy storage system. The modified pleated graphene oxide material has excellent physical/chemical properties, particularly thermal properties, mechanical strength and electrochemical properties can be greatly improved; the formed composite active substance or additive is applied to the energy storage system (such as a lithium ion battery, a lithium battery, a supercapacitor and a lithium ion capacitor), so that the electric property is improved and enhanced significantly, particularly the high-power properties and charge/discharge cycle life and stability.
