Title: High energy, long cycle life electrode for lithium-ion batteries

Abstract

Anodes for electrochemical cells and batteries are described herein. In particular, and anode comprises silicon oxide particles on a transition metal current collector (e.g., copper, nickel, copper alloy, and the like), wherein the particles comprise nanocrystalline domains of silicon dispersed within a silicon oxide matrix. The particles do not include a metal oxide coating, and are produced by heating a silicon monoxide powder at a temperature in the range of about 400 to about 1100° C. under an inert atmosphere for about 2 to about 20 hours. In some embodiments, the particles are free from a metal oxide coating and have an average diameter of about 20 to 10000 nm; the nanocrystalline domains of silicon comprise about 10 to about 90 mole percent of the particles; and the nanocrystalline domains have dimensions of about 0.2 to about 50 nm in average diameter.
