▎ 摘　　要

Porous graphene/Si-MCP (microchannel plate) microstructures are fabricated using electrochemical exfoliation and microelectronic machining. The few-layer graphene nanosheets with a lateral size of 600-850nm and thickness of 2-3nm are uniformed anchored on the surface and channels of the Si-MCP substrate. The as-prepared graphene/Si-MCP is used as the anode in lithium ion batteries and demonstrated to have a higher reversible capacity, better cycling retention, and excellent higher rate cycling performance compared to graphene/Si and Si-MCP. The good properties are attributed to the large surface-to-volume ratio of the structure and the better electrical contact with graphene. This silicon-based composite has large potential as anodes in integrated batteries.
