▎ 摘　　要

A hybrid electrode composed of silicon microchannel plates (Si MCPs) coated with nitrogen-doped graphene and TiO2 is prepared and used as the anode in a lithium-ion battery. The materials are characterized systematically by scanning electron microscopy, Raman scattering spectroscopy, X-ray photoelectron spectroscopy, and electrochemical techniques. The unique porous and ordered nanostructure of the TiO2/N-graphene/Si-MCP nanocomposite provides short paths for diffusion of Li ions and immobilized active sites, whereas N-doped graphene facilitates fast charge transportation. The synergetic effects result in high reversible specific capacities and stability. Owing to the compatibility with semiconductor processing and devices, the concept and technique have large potential in large-scale fabrication of high-performance anodes of lithium-ion batteries, especially those integrated into microelectronic chips.
