Abstract
Abstract A multilayer‐cake WS 2 /C nanocomposite was successfully synthesized through an intercalation‐transformation method, in which few‐layered WS 2 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 WS 2 /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 .
