Abstract
This application relates to anode compositions and methods of making and using the same. In particular, the anode compositions are preferably layered. Preferably, the methods of making the anode compositions comprise a surfactant mediated assembly of layers. The anode compositions have improved structural integrity and capacity while reducing capacity fade due to cycling.
