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 MoS2 nanoparticles. The MoS2@porous biochar-derived RP (MoS2@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 MoS2 nanoparticles, and an appropriate amount of TRP, the MoS2@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 MoS2@porous biochar composite is expected to become one of the most promising anode materials for LIBs.
利用天然生物质制备多孔碳具有提高锂离子电池比容量和提高倍率性能的优点。本文利用经处理的RP (TRP)制备的空心网状多孔油菜花粉碳(RPC)微球作为骨架,装载二硫化钼纳米颗粒。采用水热热解方法制备了MoS2@porous生物炭衍生RP (MoS2@RPC)负极材料。由于球形、空心和网状多孔碳骨架的协同作用,更大的比表面积,均匀分布的MoS2纳米颗粒,以及适量的TRP, MoS2@RPC-1.0 (TRP用量为1.0 g)阳极材料表现出优异的速率性能和循环稳定性。在100次循环后观察到100 mA g - 1时的高比容量为~ 800 mAh g - 1,在500次循环后也获得了500 mA g - 1时的高比容量为~ 600 mAh g - 1。总之,MoS2@porous生物炭复合材料有望成为最有前途的锂离子电池负极材料之一。
