NOVELTY - Preparation of reduced graphene oxide-lithium hydroxide microspring/wood composite electrode material, involves ultrasonically crushing lithium carbonate, graphene oxide, and deionized water, freeze-drying to obtain an aerogel of lithium carbonate and graphene oxide, removing water in the aerogel, processing in nitrogen or inert gas atmosphere for 2-5 hours at 1000-1200 degrees C to obtain obtaining reduced graphene oxide-lithium hydroxide microspring, and adding the microspring into the pore channels of carbonized wood. The ratio of lithium carbonate and graphene oxide is (0.1-0.3) mol:(0.1-0.5) g. USE - Preparation of reduced graphene oxide-lithium hydroxide microspring/wood composite electrode material for elastic capacitors and wearable capacitors used for driving electronic device (all claimed). ADVANTAGE - The method provides three-dimensional composite electrode material having high specific capacitance, high elasticity, high porosity, and high specific surface area.
