Abstract

Anodes, and battery cells utilizing the same, include silicon particles embedded within a copper matrix, wherein the anode includes 40 at. % to 75 at. % silicon. The anode can include about 21 at. % to about 67 at. % silicon particles. The copper matrix can include pure copper and/or one or more copper-silicon intermetallic phases. The copper matrix can further include one or more of nickel, gold, silver, beryllium, and zinc. The silicon particles embedded in the copper matrix can have an average particle diameter less than 10 μm. The non-surfacial silicon particles embedded in the copper matrix can be at least 99 at. % pure. The anode can be a woven mesh of ribbons or a planar sheet.
