Rate performance (discharge capacities) of SnO₂@C@half-rGO (red) and SnO₂@C/rGO (blue). The varying current is 100, 200, 500, 1000, 2000, 3000 and 5000 mA g⁻¹ for 10 cycles each, following 100–3000 mA g⁻¹ for 10 cycles each again, and 5 A g⁻¹ for 9870 cycles until the final 100 mA g⁻¹ for 10 cycles.
