Si­(CO) y (0 ≤ y ≤ 0.43) alloys were synthesized by reactive gas milling silicon in CO2 at room temperature. Silicon reacts with CO2 rapidly during milling, incorporating C and O in a 1:1 ratio to form alloys consisting of Si nanograins dispersed in an amorphous Si–O–C matrix. The capacity behavior...
