▎ 摘　　要

NOVELTY - An energy storage corrugated sandwich panel (100) comprises an upper panel (1), a lower panel (2), and an energy storage corrugated sandwich panel component (3) provided between the upper panel and lower panel. The energy storage corrugated sandwich panel component sequentially comprises an upper plate, a negative plate, a diaphragm plate, a positive plate and a lower plate. The upper and lower panels and upper and lower plates are made of insulating packaging composite material. The negative plate and the positive plate are made of modified carbon fiber material and corresponding modified active material. The diaphragm plate is made by soaking preset electrolyte. USE - Energy storage corrugated sandwich panel is used as load-bearing structural component e.g. aircraft wing surface, fuselage box and rudder surface, heat-proof, fire-proof and heat-insulating component, and damping and shock-absorbing component, and used in new energy vehicle component and high-speed rail floor. ADVANTAGE - The energy storage corrugated sandwich panel has higher structure strength, better energy storage capacity and greatly improves the robustness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the energy storage corrugated sandwich panel, which involves washing carbon fiber raw material using a mixed solution of acetone and absolute ethanol with a volume ratio of 1:1, to remove epoxy slurry coating on the surface of the carbon fiber, oxidizing the washed and dried carbon fiber using nitric acid and concentrated sulfuric acid with a volume ratio of 3:1 as oxidant to generate a predetermined concentration oxygen-containing functional group on the surface of the carbon fiber, stirring the carbon fiber and active material methanol solution, adding dimethylimidazole to generate a precursor, performing surface calcination modification treatment, synthesizing positive and negative plates with active material adhered to the surface, bonding positive tab on the positive plate with conductive silver paste, and negative tab on the negative plate, soaking the diaphragm plate in the lithium salt electrolyte in an inert gas environment, such that the electrolyte completely penetrates into the diaphragm plate, infiltrating the fiber-reinforced upper plate and the lower plate with resin, laying corrugated plate in corresponding order, solidifying into energy storage corrugated sandwich panel component through pultrusion or compression molding, adhering an adhesive film on the inside of the upper panel and the lower panel, and bonding the energy storage corrugated sandwich component. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the energy storage corrugated sandwich panel.
