英文摘要	Lithium-ion batteries are widely used in various fields of social life because of their good cycle performance and high energy density. The excellent performance of the anode electrode material directly determines the performance of the prepared battery. In recent years, bimetallic oxides with the spinel structure have been widely studied. However, the volume change in its structure during charge and discharge leads to its electrochemical instability, which cannot meet the needs of lithium batteries. Inspired by this, the NiGa2O4/RGO composite electrode material with a special structure was successfully designed and prepared by a simple hydrothermal method and subsequent heat treatment. The electrochemical properties of composites and pure materials are analyzed and compared. From the test results, it can be seen that NiGa2O4/RGO has outstanding electrochemical properties and fast kinetic behavior. After 200 charge/discharge cycles, the discharge specific capacity of the composite NiGa2O4/RGO is stably maintained at 610.5 mA h g-1 and the Coulomb efficiency can reach about 99%. Moreover, in this article, we analyzed the capacitance characteristics of NiGa2O4/RGO rarely reported in other articles, which enriched the research on the electrochemical properties of such substances. Finally, it contributes to promoting the feasibility of such bimetallic oxides in practical applications. © 2022 American Chemical Society
