Abstract
Developing next-generation anode materials is crucial for advancing lithium-ion batteries, particularly in terms of capacity, safety, and cycling stability. While tin (II) selenide (SnSe) boasts a high theoretical capacity, its practical application is hindered by poor stability and volume expansion during cycling. To address these challenges, we combined commercially available SnSe with Ti3C2Tx MXene, which shows metallic conductivity and excellent binding properties. This study shows that a composite anode comprising SnSe and Ti3C2Tx needs no additional additives and has a minimal dead volume. Electrochemical evaluation demonstrated that our composite outperforms traditional anode materials due to the intrinsic MXene pseudo-capacitance and redox activity. The composite reached 918 mAh/g(total) (1148 mAh/g(SnSe)) at 0.2 C for 170 cycles and 720 mAh/g(total) (900 mAh/g(SnSe)) at 150 cycles at charge-discharge rates of 0.2 C and 0.5 C, respectively. This makes our hybrid structure a promising candidate for high-performance energy storage devices.
