摘要：
A multilayer-cake WS2/C nanocomposite was successfully synthesized through an intercalation-transformation method, in which few-layered WS2 and carbon were sandwiched in an alternating sequence. As a benefit of the electronic conductivity enhanced by the interlayer carbon and the unique "regular" and "alternate" architecture, the WS2/C nanocomposite showed promising performance as an anode material for lithium-ion batteries. The nanocomposite demonstrated a high capacity of 829.4 mAh.g(-1) at 0.3 A.g(-1) after 140 cycles and it could still deliver a stable capacity of about 326.8 mAh.g(-1) at a current density of 8.0 A.g(-1).
