Abstract
The present invention provides anodes comprising an electrically conductive substrate, comprising at least one non-uniform surface; and a random network of silicon nanowires (Si NWs) chemically grown on said at least one non-uniform surface of the substrate, wherein the Si NWs have at least about 30% amorphous morphology, and methods of manufacturing of the anodes. Further provided are lithium ion batteries comprising said anodes.
