The molybdenum disulfide/reduced graphene oxide@polyaniline (MoS2/RGO@PANI) was facilely and effectively prepared through a two-stage synthetic method including hydrothermal and polymerized reactions. The rational combination of two components allowed polyaniline (PANI) to uniformly cover the outer face of molybdenum disulfide/reduced graphene oxide (MoS2/RGO). The interaction between the two initial electrode materials produced a synergistic effect and resulted in outstanding energy storage performance in terms of greatest capacitive property (1224 F g(-1) at 1 A g(-1)), good rate (721 F g(-1) at 20 A g(-1)), and cyclic performance (82.5% remaining content after 3000 loops). The symmetric cell with MoS2/RGO@PANI had a good capacitive property (160 F g(-1) at 1 A g(-1)) and energy and power density (22.3 W h kg (-1) and 5.08 kW kg(-1)).
二硫化钼/还原氧化石墨烯@聚苯胺（MoS2/RGO@PANI）通过包括水热和聚合反应的两步合成方法简便有效地制备。两种组分的合理组合使聚苯胺（PANI）均匀地覆盖在二硫化钼/还原氧化石墨烯（MoS2/RGO）的外表面。两种初始电极材料之间的相互作用产生协同效应，从而在最大电容性能（1 A g(-1) 时为 1224 F g(-1)）、良好的倍率性能（20 A g(-1) 时为 721 F g(-1)）和循环性能（3000 次循环后剩余容量为 82.5%）方面表现出优异的储能性能。具有 MoS2/RGO@PANI 的对称电池具有良好的电容性能（1 A g(-1) 时为 160 F g(-1)）和能量和功率密度（22.3 W h kg(-1) 和 5.08 kW kg(-1)）。
