- Abstract
- A facile and scalable wet ball-milling method was employed to reduce the size of two-dimensional (2D) materials (MoS2, MoSe2, and NbSe2) and distribute these particles on a graphite surface. Herein, we discuss the effects of graphite matrix addition on the performance of each of the 2D materials prepared via a wet ball-milling process, and demonstrate that these composites can be used as high-performance anode materials for sodium-ion batteries. As compared to the MoSe2@graphite and NbSe2@graphite composites, the MoS2@graphite electrode exhibited superior electrochemical performance, with high specific capacity (i.e., similar to 300 mAh g(-1) after 100 cycles, corresponding to similar to 77% of charge capacity retention relative to the initial charge capacity), high cyclic stability, and excellent rate capability (similar to 85% capacity retention at 10 A g(-1) relative to the capacity at 0.1 A g(-1)).
