摘      要：Based on the great advantages of an inner hollow structure and excellent solid counterpart capacity,complex hierarchical structures have been widely used as electrodes for lithium-ion ***,hierarchical yolk-shell Cu_(2)O@Cu O-decorated RGO(YSRs)was designed and synthesized via a multistep ***-like Cu_(2)O-decorated RGO was firstly produced,in which GO was reduced slightly while cuprous oxide was ***,the controlled oxidation of Cu_(2)O@RGO led to the synthesis of special YSRs,which were composed of a solid Cu_(2)O core,spur-CuO,CuO shell,and RGO *** anode materials,YSRs could provide considerable capacity ***,the void existed between shells and solid active materials retaining the advantages of inner hollow *** a result,the unique architecture of the materials renders the composites with enhanced electronic and ionic diffusion kinetics,high specific capacity(~894 m Ah g^(-1),0.1 C),and an excellent rate capability.
