Silicon alloys have the highest specific capacity when used as anode material for lithium-ion batteries, however, the drastic volume change inherent in their use causes formidable challenges toward achieving stable cycling performance. Large quantities of binders and conductive additives are typically necessary to maintain good cell performance. In one embodiment of the invention, only 2% (by weight) functional conductive polymer binder without any conductive additives was successfully used with a micron-size silicon monoxide (SiO) anode material, demonstrating stable and high gravimetric capacity (>1000 mAh/g) for .about.500 cycles and more than 90% capacity retention. Prelithiation of this anode using stabilized lithium metal powder (SLMP.RTM.) improves the first cycle Coulombic efficiency of a SiO/NMC full cell from .about.48% to .about.90%. This combination enables good capacity retention of more than 80% after 100 cycles at C/3 in a lithium-ion full cell.
