In this study, we adopted a novel method to synthesize a rice husk-derived carbon@SnO 2 @reduced graphene oxide (rGO)composite with a multi-level structure as an anode electrode for lithium-ion batteries. The carbon source of composite was cellulose extracted from RH. The material exhibits excellent performance of LIBs with large reversible capacity and outstanding cycle performance. It shows a reversible capacity of 1206.9 mAhg −1 at a current density of 0.2C after 100 cycles. Excellent cycle performance is due to unique multi-level structure, which increases active site of lithium ion. Furthermore, SnO 2 nanoparticles (SnO 2 NPs) and carbon skeleton have strong chemical bonds to prevent SnO 2 NPs from falling out of the three-dimensional network during cycling., thereby making material a promising anode material for LIBs.
