Transition metal sulfides have received broad research and application development for lithium-ion batteries owing to their rare physical/chemical characteristics. Unfortunately, the fundamental flaws of volume expansion and poor electrical conductivity have hampered 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
