▎ 摘  要

NOVELTY - The method involves (i) mixing the ethanol solution of oxidized graphene and iron(III) chloride hexahydrate, performing hydrothermal reaction, washing and vacuum drying to obtain fluorine-doped reduced graphene oxide; (ii) preparing a mixed solution of silver nitrate, sodium citrate tribasic dihydrate, polyvinylpyrrolidone and hydrogen peroxide, adding the prepared mixed solution into fluorine-doped reduced graphene oxide, adding sodium borohydride solution, stirring and centrifuging; (iii) mixing the amine-functionalized-reduced graphene oxide material with polyvinylidene fluoride and organic solvent to obtain a slurry, coating the slurry on a carbon cloth and drying; and (iv) stacking the cathode material, membrane, carbon cloth-loaded amine-functionalized-reduced graphene oxide anode and anode current collector, packaging between the electrode shells, adding electrolyte and finishing the assembly of CR2025 button lithium-nitrogen battery in the glove box filled with argon gas. USE - The method is useful for manufacturing a light-assisted lithium-nitrogen battery i.e. lithium-ion battery. ADVANTAGE - The lithium-nitrogen battery can realize nitrogen electrochemical reduction under the normal temperature condition, without high temperature and high pressure and has low raw material, low energy consumption, simple assembling technique, high circulating efficiency, good multiplying power performance, long circulating service life, large scale production and preparation, and wide application prospect.
