This study utilizes mushroom stalks as a biological template and melamine as a precursor for carbon nitride to synthesize g-C3N4/C，via thermal polymerization method. Copper sulfate pentahydrate （CuSO4·5H2O），ammonium molybdate tetrahydrate （（NH4）6Mo7O24·4H2O），and thiourea （CH4N2S） are selected as the sources for Cu，Mo，and S，respectively. A two-step hydrothermal process is employed to prepare CuS/MoS2 composites with different mass ratios. Then CuS/MoS2 is anchored on the surface of g-C3N4/C to obtain CuS/MoS2-g-C3N4/C composite electrode materials. The composite electrode materials are characterized by their phase structure，microstructure，pore structure，and capacitance performance. The results indicate that the CuS/MoS2-g-C3N4/C composite electrode materials exhibit high purity，good crystallinity，good phase contact interface， and abundant porous structure. In electrochemical performance testing，the CuS/MoS2 composite material with a mass ratio of MoS2 to CuS at 1∶2 demonstrates optimal electrochemical performance，achieving a specific capacitance of 230 F·g-1 at a current density of 1 A·g-1. When the mass ratio of CuS/MoS2 to g-C3N4/C is 1∶1，the CuS/MoS2-g-C3N4/C composite material exhibits the best electrochemical performance，with a specific capacitance of 434.7 F·g-1. Moreover，after 1000 cycles，the capacitance retention rate is 89.2%，showing good stability.
