▎ 摘  要

Hollow cobalt oxide nanoparticles embedded porous reduced graphene oxide hybrids are constructed by means of a facile etching strategy and the Kirkendall effect. When examined as an anode for lithium-ion batteries, this unique structured composite exhibits remarkable lithium storage capability such as excellent rate capability, superior reversible specific capacity together with good cycling durability, highlighting the importance of embedding active materials on graphene sheets for maximum utilization of hollow structured cobalt oxide and porous reduced graphene oxide for energy devices.
