In everyday life, superior lithium-ion batteries (LIBs), with fast charging ability, have become valuable assets. The LIB performance of an anode composite copper cobalt tin sulphide (CuCoSnS; CCTS) electrode, which was fabricated using a simple and easy hydrothermal method, was investigated. The electrochemical charge storage performance of the CCTS anode demonstrated sustainability, high-rate capability and efficiency. The CCTS anode exhibited a first discharge capacity of 914.5 mA h g and an average specific capacity of 198.7 mA h g in consecutive cycles at a current density of 0.1 A g. It had a capacity retention of ∼62.0% and a coulombic efficiency of more than 83% after over 100 cycles, demonstrating its excellent cycling performance and reversibility. It can be an alternative anode to other established electrode materials for real battery applications.
在日常生活中，具有快速充电能力的优质锂离子电池（LIBs）已成为宝贵资产。研究了采用简单易行的水热法制备的阳极复合铜钴锡硫化物（CuCoSnS；CCTS）电极的LIB性能。CCTS阳极的电化学电荷存储性能表现出可持续性、高倍率性能和效率。在0.1 A g的电流密度下，CCTS阳极在连续循环中首次放电容量为914.5 mA h g，平均比容量为198.7 mA h g。经过100多次循环后，其容量保持率约为62.0%，库仑效率超过83%，证明了其优异的循环性能和可逆性。在实际电池应用中，它可以作为其他既定电极材料的替代阳极。
