Abstract
In this study, we adopted a novel method to synthesize a rice husk-derived carbon@SnO2@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, SnO2 nanoparticles (SnO2 NPs) and carbon skeleton have strong chemical bonds to prevent SnO2 NPs from falling out of the three-dimensional network during cycling., thereby making material a promising anode material for LIBs.
