Introduction: Lithium/sodium ion battery has the disadvantages of low power density and short service life. Among them, it is difficult for the cathode material to meet the high lithium/sodium storage capacity, high electrical conductivity and excellent structural stability at the same time, resulting in its poor lithium/sodium storage performance, which is an important factor limiting the development of lithium/sodium ion batteries. The main purpose of our work is to prepare carbon supported nanocomposite electrode materials with RGO, CNTs and CNFs as substrates and components of electrode composites, and to improve the poor electrochemical lithium/sodium storage performance of pure single component electrode materials by compounding SnO2, MoO2, building suitable nanostructures and doping heterogeneous atoms, so that they can show excellent electrochemical lithium/sodium storage performance and charge/discharge stability. cycle stability. The proposed carbon material modification, nanostructure construction strategy and electrochemical performance study under the care and guidance of Mr. Huang during his school years provide the reference and basis for improving the electrochemical lithium/sodium storage performance of such materials.
