▎ 摘 要
A graphene-wrapped SiO2 nanotube network (SiO2-NT/G network) was designed and synthesized through a ZnO-nanorod-templated self-assembly approach. When utilized as an anode material in Li-ion batteries, the as-synthesized SiO2-NT/G network manifests good lithium-storage performance in terms of specific capacities, cycle life, and rate capability.
