Abstract
-
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. © 2011 the Owner Societies.
