Abstract
An electrochemically active material includes a silicon alloy material having the formula: SiwM1xCyOz, where w, x, y, and z represent atomic % values and w+x+y+z=1; M1 comprises a transition metal; w>0; x>0; y≥0; and z≥0. The electrochemically active material also includes a metal-based material having the formula: M2aObAc, where a, b, and c represent atomic % values and a+b+c=1; M2 comprises a metal; A is an anion; a>0; b≥0; and c≥0.
