Figure 4From: Reduced graphene oxide/carbon double-coated 3-D porous ZnO aggregates as high-performance Li-ion anode materialsElectrochemical properties. Charge–discharge curves of the (a) bare ZnO, (b) C/ZnO, (c) RGO/ZnO, and (d) RGO/C/ZnO. (e) Cycle-life performances of the RGO/C/ZnO, RGO/ZnO, C/ZnO, and bare ZnO. (f) Rate capability of the RGO/C/ZnO, RGO/ZnO, and C/ZnO (1 C = 978 mA/g).Back to article page
