文摘
Antimony/porous biomass carbon nanocomposites have been prepared by a chemical reduction method and applied as anodes for sodium-ion batteries. The porous biomass carbon derived from a black fungus had a large Brunauer–Emmett–Teller (BET) surface area of 2233 m2 g−1 in which antimony nanoparticles were uniformly distributed in the porous carbon. The as-prepared antimony/porous biomass carbon nanocomposites exhibited a high reversible sodium storage capacity of 567 mA h g−1 at a current density of 100 mA g−1, extended cycling stability, and good rate capability.
