▎ 摘　　要

NOVELTY - Ferric selenide (Fe3Se4)/graphene sodium battery anode material, comprises Fe3Se4 nanoparticles are uniformly distributed on the two-dimensional graphene. USE - Used as ferric selenide (Fe3Se4)/graphene sodium battery anode material. ADVANTAGE - The material improves electrochemical activity of the material, inhibites Fe3Se4 particle aggregation, adjusting volume change of Fe3Se4 in the charging and discharging process, realizing fast diffusion of electron and fast transfer of electrolyte ion, provides a new idea for the exploration and design of the high performance electrode material of the sodium battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the ferric selenide (Fe3Se4)/graphene sodium battery anode material.
