MoS ₂ @porous biochar derived from rape pollen as anode material for lithium‐ion batteries

Abstract Preparation of porous carbon from natural biomass offers attractive features to facilitate the specific capacity and promote the rate capability of lithium‐ion battery (LIB). Herein, the hollow mesh porous rape pollen carbon (RPC) microsphere derived from treated RP (TRP) was utilized as a skeleton to load MoS 2 nanoparticles. The MoS 2 @porous biochar‐derived RP (MoS 2 @RPC) anode materials were obtained by the hydrothermal–pyrolysis route. Attributing to the synergistic effect of spherical, hollow, and mesh porous carbon skeletons, larger specific surface areas, evenly distributed MoS 2 nanoparticles, and an appropriate amount of TRP, the MoS 2 @RPC‐1.0 (TRP amount of 1.0 g) anode material reveals exceptional rate capability and cycling stability. A high specific capacity of ∼800 mAh g −1 at 100 mA g −1 is observed after 100 cycles, and that of ∼600 mAh g −1 at 500 mA g −1 is also obtained after 500 cycles. In conclusion, the MoS 2 @porous biochar composite is expected to become one of the most promising anode materials for LIBs.
