Abstract: An electrochemically active material includes silicon and a transition metal. At least 50 mole % of the transition metal is present in its elemental state, based on the total number of moles of transition metal elements present in the electrochemically active material. An electrochemically active material includes silicon and carbon. At least 50 mole % of the carbon is present in its elemental state, based on the total number of moles of carbon present in the electrochemically active material.
