Abstract

In everyday life superior lithium-ion batteries (LIB) with fast charging ability have become a valuable asset. The LIB performance of anode composite copper cobalt tin sulphide (Cu2CoSnS4; CCTS) electrodes, which were 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 mAhg−1 and an average specific capacity of 198.7 mAhg−1 in consecutive cycles at a current density of 0.1 Ag−1. 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.
