Biomass materials have aroused much concern in functional composites because of the unique bio-mesopores structure, recyclability and electrochemical properties. Thus, it is very promising to manufacture the mushroom-derived carbon/NiO functional composite (MC/NiO-FC). The experimental results manifest that MC/NiO-FC has bio-mesopores structure and the sizes of pores are about 3.5 nm. Furthermore, the specific surface area of MC/NiO-FC is 174 m2 g−1. As an anode material, the MC/NiO-FC shows a reversible capacity of 887.5 mAh g−1 after 300 cycles at a current density of 100 mA g−1, about three times than that of MC (～262 mAh g−1). The good electrochemical performances can be imputed to the bio-mesopores structure and synergistic effect between MC and NiO particles. •Mushroom-derived carbon (MC) has been selected as a matrix, showing good electrochemical stability.•An effective route for manufacturing the mushroom-derived carbon/NiO/C functional compositehas been developed.•The MC/NiO-FC shows an excellent electrochemical performance of 887.5 mAh g−1 after 300 cycles.
