▎ 摘　　要

NOVELTY - An electrochemical energy conversion and storage device (300) comprises pair of current collectors (310,315), graphene film (320) as anti-corrosion protective layer, on each of the pair of current collectors, and electrolyte (350) between the pair of current collectors. The graphene film is impermeable to gas and ion diffusion. USE - Electrochemical energy conversion and storage device e.g. battery, supercapacitor, fuel cell, electrolytic cell or dye- sensitized solar cell (all claimed). ADVANTAGE - The electrochemical energy conversion and storage device is economical. The graphene film in the electrochemical energy conversion and storage device has excellent chemical stability and mechanical stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of corrosion-and oxidation-resistant current collector. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrochemical energy conversion and storage device. Electrochemical energy conversion and storage device (300) Current collector (310,315) Graphene film (320) Cathode material (330) Electrolyte (350)
