摘要：

Rice husk (RH) was employed as a precursor for the preparation of disordered carbon for lithium-ion batteries. Disordered carbon was synthesized by pyrolysis of RH under an inert gas atmosphere followed by base treatment to remove the silica fraction. These carbons were characterized through X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) measurements, scanning electron microscopy (SEM), Raman spectroscopy and transmission electron microscopy (TEM). The effects of reaction temperature for NaOH treatment on the capacity of these carbons were described. These carbons showed a high reversible capacity of 502 mA h g(-1) after 100 cycles at 0.2 C in lithium-ion battery anodes.
