CuS and CuS have been investigated respectively as anodes of lithium-ion batteries because of their abundant resources, no environment pollution, good electrical conductivity, and a stable discharge voltage plateau. In this work, CuS/CuS nanocomposites were firstly prepared simultaneously by the one-pot synthesis method at a relatively higher reaction temperature 200 °C. The CuS/CuS nanocomposites anodes exhibited a high initial discharge capacity, an excellent reversible rate capability, and remarkable cycle stability at a high current density, which could be due to the nano-size of the CuS/CuS nanocomposites and the assistance of CuS. The high electrochemical performance of the CuS/CuS nanocomposites indicated that the CuS nanomaterials will be a potential lithium-ion battery anode.
由于其资源丰富、无污染、良好的导电性以及稳定的放电电压平台，硫化铜（CuS）和硫化铜已分别作为锂离子电池的阳极进行了研究。在这项工作中，首先通过一锅合成法在相对较高的反应温度200°C下同时制备了硫化铜/硫化铜（CuS/CuS）纳米复合材料。硫化铜/硫化铜纳米复合材料阳极表现出高初始放电容量、优异的可逆倍率性能以及在高电流密度下显著的循环稳定性，这可能归因于硫化铜/硫化铜纳米复合材料的纳米尺寸以及硫化铜的辅助作用。硫化铜/硫化铜纳米复合材料的高电化学性能表明，硫化铜纳米材料将是一种潜在的锂离子电池阳极。
