过渡金属硫化物作为高性能超级电容器的电极材料具有广阔的应用前景。在这里，原位水热法被开发用于合成NiS 2/MoS 2（NMS）纳米线支撑在泡沫镍，促进电解质离子和电子的传输。由于结构和成分的优点，NiS 2/MoS 2电极在5 mA cm（-2）下表现出4.46 F cm（-2）的高面电容和优异的循环稳定性。此外，组装了NiS 2/MoS 2//AC混合超级电容器，其在3.63 mW cm（-2）的功率密度下提供0.35 mWh cm（-2）的能量密度，并且在3000次循环后具有92.4%的电容保持率。本工作提出了一种简便的原位水热法制备高性能无粘结剂电极。(C)2019 Elsevier B.

Transition metal sulfides are promising as electrode materials for high-performance supercapacitors. Here, an in-situ hydrothermal method is developed for synthesis of NiS2/MoS2 (NMS) nanowires supported on Ni foam that facilitate the transport of electrolyte ions and electrons. Owing to the structural and compositional benefits, the NiS2/MoS2 electrode exhibits a high areal capacitance of 4.46 F cm(-2) at 5 mA cm(-2) and excellent cycle stability. In addition, the NiS2/MoS2//AC hybrid supercapacitor was assembled, which delivers an energy density of 0.35 mWh cm(-2) at a power density of 3.63 mW cm(-2), and 92.4% capacitance retention after 3000 cycles. The work presents a facile in-situ hydrothermal method to synthesize high-performance binder-free electrode. (C) 2019 Elsevier B.V. All rights reserved.
