Three-dimensional porous silicon-MWNT heterostructure with superior lithium storage performance

摘要

A novel three-dimensional porous Si-MWNT heterostructure was designed to meet the demand of high-capacity and long-life lithium storage. This material presented a stable capacity above 1000 mAh g~(-1) for nearly 200 cycles, which benefited from its highly porous structure combined with robust MWNT connections that accommodated the host volume change and improved the electric conductivity.
