▎ 摘　　要

NOVELTY - The method involves preparing anode and cathode substrates, where the bottom electron conducting layer of the bioanode and the bottom electron conducting layer of the biocathode are prepared on the anode and cathode substrates. The carbon nanotubes are activated, and the mixture of activated carbon nanotubes and naphthoquinone is placed in a vacuum ball milling tank. The modified carbon nanotubes are mixed with acetic acid, glutaraldehyde, deionized water, chitosan and oxidase, and stirred to obtain a sol-shaped anode material. The vacuum ball milling tank is vacuumized and nitrogen gas is injected to perform planetary ball milling to obtain nitrogen-doped carbon nanotubes. The nitrogen-doped carbon nanotubes are mixed with perfluoro resin and deionized water, and stirred to obtain a sol-shaped cathode material. The surface is etched with hydrogen plasma to form an anode nickel-plated substrate and a cathode gold-plated substrate. USE - Method used for preparing electronic skin biofuel cell (claimed) with high power density. ADVANTAGE - The method utilizes the bonding of graphene and carbon nanotube to obtain a fast electron transmission path, and then modifies the carbon nanotube to obtain a flexible biofuel cell with high power density.
