Abstract

SnO₂@C/graphene ternary composite material has been prepared via a double-layer modified strategy of carbon layer and graphene sheets. The size, dispersity, and coating layer of SnO₂@C are uniform. The SnO₂@C/graphene has a typical porous structure. The discharge and charge capacities of the initial cycle for SnO₂@C/graphene are 2,210 mAh g⁻¹ and 1,285 mAh g⁻¹, respectively, at a current density of 1,000 mA g⁻¹. The Coulombic efficiency is 58.60%. The reversible specific capacity of the SnO₂@C/graphene anode is 955 mAh g⁻¹ after 300 cycles. The average reversible specific capacity still maintains 572 mAh g⁻¹ even at the high current density of 5 A g⁻¹. In addition, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) are performed to further investigate the prepared SnO₂@C/graphene composite material by a microwave hydrothermal method. As a result, SnO₂@C/graphene has demonstrated a better electrochemical performance.
