摘要
A liquid exfoliation route has allowed the environmentally friendly, scalable, and cost-effective production of high-quality 2D MoS2 nanosheets. However, high capacity achieved by the liquid-exfoliated pristine MoS2 is rarely reported in lithium- ion batteries. For the first time, it is demonstrated that liquid-exfoliated small-sized MoS2 nanosheets exhibit a high reversible capacity of 1133 mAhg(-1) after 130 cycles and an excellent rate capability; these values are comparable to the high performances achieved by the available chemical routes.
