Abstract
To investigate the effects of carbon nanotube content on the electrochemical performance in MoS₂/CNT nanocomposite, a simple high-energy mechanical milling method was employed to prepare nanocomposites from MoS₂ and CNT. Prepared with a one-step, 24-h ball-milling method, the MoS₂/CNT nanocomposite showed improved performance in terms of specific capacity after 70 cycles when compared to pure MoS₂. In addition, upon studying the effects of the weight ratio between MoS₂ and the CNTs at (1:2), (1:1), and (2:1), we found the MoS₂/CNT-(1:2) showed the highest specific capacity (~765 mAh g-1) after 70 cycles and the best rate capability due to increased conductivity. Overall, the results suggested that the addition of conductive CNTs in MoS₂ not only improves the cycling stability, but also leads to an increase in the specific capacity of MoS₂/CNTs, which suggests our MoS₂/CNT nanocomposite as a new and promising anode material for lithium-ion batteries (LIBs).
