Abstract

Transition Metal Sulfides (TMSs) have received broadly research and application in the Lithium-ion Batteries (LIBs) field owing to their rare physical/chemical characteristics. Unfortunately, the fundamental flaws of volume expansion and poor electrical conductivity hampered its future practical implementation. Herein, a carbonization/activation procedure coupled with a facile solvothermal method and post-annealing strategy were developed to synthesize hollow tubular biomass-derived carbon (HBC) loaded NiS/C composite. The HBC serves a dual functional by providing highly active surface sites for NiS/C particles loading and naturally existing micron-level pores that can accommodate the volume variation. As a consequence, the HBC-NiS/C anode displayed strong lithium-ion storage performances with a high specific capacity (652 mAh g−1 at 0.2 A g−1 over 100 cycles), favorable rate capability, and exceptional structural durability.
