Carbon-Coated Coaxial Cable-like ZnO@SiO@C for High-Performance Lithium-Ion Battery Anode Materials.

The practical applications of SiO anode material are limited by large volume changes and poor electronic conductivity. To reduce the effects of these problems, a carbon-coated coaxial cable-like ZnO@SiO@C composite material was prepared. ZnO has a certian electronic conductivity and an electrochemical activity, and the carbon layer can alleviate the volume variation of SiO, effectively improving the electronic conductivity and structural stability.
