▎ 摘　　要

NOVELTY - An electrode material (100) comprises a laminate (120) in which reduced graphene oxides (110) are laminated, containing an ionic liquid (130) between the reduced graphene oxides. USE - Electrode material is used for electrode for electrical storage device e.g. electric double layer capacitor and lithium-ion battery (all claimed). Uses include but are not limited to wind power generation, electric vehicle, notebook personal computer and mobile telephone. ADVANTAGE - The electrode comprising the electrode material provides electrical storage device having improved rate characteristics by using ionic liquid as the electrolyte, and charging/discharging characteristics, and high power density, and energy density. The laminate has high specific surface area, and low surface free energy of reduced graphene oxides, when ionic liquid is located between the reduced graphene oxides, and increases path of ion diffusion and promotes ion transport electrolyte, when reduced graphene oxides are separated by ionic liquid. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of electrode material; and (2) electrical storage device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrode material.
