Abstract

CUITent LiB technology relies on graphitic carbon as the anode material, with a theoretical capacity of 372 mAh/g. In order to increase the energy density of LiBs, anode materials with a greater capacity for lithium storage are under intense investigation. Materials which form alloys with lithium such as antimony, germanium, silicon, and tin, all have theoretical capacities which far surpass graphite. However silicon, as the most naturally abundant e1ement and possessing a theoretical capacity of 3579 mAh/g in the Li$_{15}$Si$_4$ alloy, is the most promising for global adoption in next generation LiBs.
