核壳结构Si@V2O5@PPy负极材料的制备及电化学性能研究
Preparation and electrochemical performance of core-shell structured Si@V2O5@PPy anode material
摘要
Abstract
In this paper,a core-shell structured Si@V2O5@PPy anode material was prepared by coating V2O5/polypyrrole double layers on the surface of nano-silicon spheres through solvothermal method and in-situ gas-phase polymerization.The results showed that the double coating layers not only improved the electron and ion transport properties of the composite material,but also effectively suppressed the electrode failure caused by the volume change of silicon material through the design of the core-shell structure and the selection of composite material components.Therefore,the battery with this material exhibited excellent cycling stability and rate performance.关键词
