Abstract Aligned reclaimed carbon fiber (RCF) was reused as a conductive support to load hierarchical molybdenum disulfide (MoS2) spheres and thus MoS2/RCF composite was constructed. The synthesis of MoS2 and its loading were simultaneously completed during a facile hydrothermal process. This MoS2/RCF was directly utilized as the negative electrode for supercapacitor without any further process, which exhibited superior electrochemical performance: A specific capacitance of 225 F g−1 at 0.5 A g−1. Furthermore, an asymmetric supercapacitor (ASC) was assembled by coupling this MoS2/RCF electrode (−) with MnO2/RCF electrode (+), which delivered an energy density of 22.5 W h kg−1 at a power density of 703 W kg−1 over a wide potential range of 1.7 V. This RCF may be a promising conductive support candidate for those electrodes in the energy storage devices.

用于高性能超级电容器的 MoS 2 /RCF 电极的简易构建

摘要 对齐再生碳纤维（RCF）被重新用作导电载体以负载分级二硫化钼（MoS2）球体，从而构建了MoS2/RCF复合材料。MoS2 的合成及其负载是在一个简单的水热过程中同时完成的。这种 MoS2/RCF 直接用作超级电容器的负极，无需任何进一步处理，表现出优异的电化学性能：0.5 A g-1 时的比电容为 225 F g-1。此外，通过将该 MoS2/RCF 电极 (-) 与 MnO2/RCF 电极 (+) 耦合来组装不对称超级电容器 (ASC)，在 703 W kg- 的功率密度下提供 22.5 W h kg-1 的能量密度1 在 1.7 V 的宽电位范围内。
