Abstract
Electrodes comprising an alkali metal, for example, lithium, alloyed with nanostructured materials of formula SiGe, where 0<z≦1; formula SiGe, where 0<z<1; and/or germanium exhibit a combination of improved capacities, cycle lives, and/or cycling rates compared with similar electrodes made from graphite. These electrodes are useful as anodes for secondary electrochemical cells, for example, batteries and electrochemical supercapacitors.
