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 m 2 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.
