摘　　要：采用两步水热法,将Co-Ni-S与Mo_(2)TiC_(2)MXene结合,呈褶皱状薄层的MXene均匀地包覆在Co-Ni-S蜂窝状片层表面,成功制备出复合电极材料Co-Ni-S/MXene。电化学性能研究表明,得益于MXene的本征高导电性,复合电极材料Co-Ni-S/MXene展示出比Co-Ni-S更高的比电容和倍率性能及较低的电荷转移和离子扩散电阻。此外,Co-Ni-S/MXene具有良好的稳定性和库伦效率,是优异的超级电容器电极材料。Co-Ni-S/MXene composite electrode material was successfully synthesized through a two-step hydrothermal method,combining Co-Ni-S with Mo_(2)TiC_(2)MXene.The folded MXene exhibited uniform coating on the surface of the Co-Ni-S honeycomb sheet.The electrochemical performance of the Co-Ni-S/MXene composite electrode material demonstrated higher specific capacitance and rate performance,as well as lower charge transfer and ion diffusion resistance compared to pure Co-Ni-S due to the intrinsic high conductivity of MXene.Furthermore,Co-Ni-S/MXene displayed excellent stability and coulombic efficiency,making it an excellent candidate for supercapacitor applications.
