▎ 摘　　要

NOVELTY - The method comprises (1) dissolving tin chloride in concentrated hydrochloric acid to form a stable acidic tin chloride solution, (2) oxidizing the bacterial cellulose slurry through 2,2,6,6-tetramethylpiperidine oxide to obtain oxidized bacterial cellulose (OBC), and configuring into an oxidized bacterial cellulose solution, (3) mixing the acidic tin chloride solution, oxidized bacterial cellulose solution, and graphene oxide dispersion in a hydrothermal kettle, stirring to form a uniform mixed solution, and performing hydrothermal treatment, and (4) cooling the hydrothermal kettle to room temperature, centrifuging the product, washing with water and ethanol, and freeze-drying. USE - Method for preparing tin dioxide-oxidized bacterial cellulose/reduced graphene oxide electrode material. ADVANTAGE - The method is simple and environmentally friendly, and has low energy consumption. The electrode material has excellent electrochemical performance.
