▎ 摘　　要

NOVELTY - The method involves adding ball-shaped graphite oxide into a ball mill for ball milling. The ball-shaped graphite oxide is added into water to disperse a mixture to form a suspension. Metal salt of aluminum sulfate or magnesium sulfate or aluminum chloride is added to the suspension to prepare an electrolyte solution. A graphite electrode and a nickel foam electrode are inserted into an electrolyte, and respectively connected to positive and negative power supplies. The nickel foam electrode is removed. Solvent is evaporated. USE - Method for preparing electrodeposited graphene foam for use in an electrochemical energy storage device. ADVANTAGE - The method enables preparing graphene with better electrical, thermal, optical and mechanical properties in an easy manner by using a simple device. The method enables improving conductivity and chemical stability of the graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for preparing electrodeposited graphene foam. '(Drawing includes non-English language text)'
