Hierarchical tubular structures constructed by carbon-coated SnO2 nanoplates for highly reversible lithium storage

Abstract

Hierarchical tubular structures constructed by ultrathin carbon-coated SnO2 nanoplates are rationally designed and synthesized. This interesting structure simultaneously integrates the structural and compositional design rationales for high-energy anode materials based on low-dimensional ultrathin nanoplates, a hollow tubular structure, and a carbon nanocoating. When evaluated as an anode material for lithium-ion batteries, the as-synthesized SnO2-carbon hybrid structure manifests high specific capacity and excellent.
