Currently, ternary CuCoS sulfides are intensively investigated as electrode materials for electrochemical capacitors due to their low cost, high conductivity, and synergistic effect. The research of CuCoS materials for energy storage has gradually grown from 2016. The supercapacitive performances of CuCoS electrodes for electrochemical capacitors are briefly reviewed in this work. The structure, morphology, and particle size of CuCoS are related to the synthesis conditions and electrochemical performances. The thin films of CuCoS nanostructures deposited on conductive substrates and their composites both show better properties than single CuCoS. CuCoS and its composites reveal large potential for asymmetric capacitors, delivering high energy densities. However, there is still much new space remaining for future research. The possible development directions, challenges, and opportunities for CuCoS materials are also discussed.
目前，三元硫化铜钴由于其低成本、高导电性和协同效应，作为电化学电容器的电极材料受到了广泛研究。对硫化铜钴材料用于储能的研究自2016年以来逐渐兴起。本文简要综述了用于电化学电容器的硫化铜钴电极的超级电容性能。硫化铜钴的结构、形态和粒径与合成条件及电化学性能相关。沉积在导电基底上的硫化铜钴纳米结构薄膜及其复合材料均表现出比单一硫化铜钴更好的性能。硫化铜钴及其复合材料在不对称电容器方面展现出巨大潜力，可提供高能量密度。然而，未来研究仍有很大的新空间。本文还讨论了硫化铜钴材料可能的发展方向、挑战和机遇。
