Anodes for batteries based on tin-germanium-antimony alloys

摘要

An anode for a battery including an electrochemically active material including a ternary alloy of tin (Sn), germanium (Ge), and antimony (Sb). A battery including the anode, a cathode, a separator, and an electrolyte. The ternary alloy may include SnxGeySbz, where x+y+z=100, and x≥y or x≥z. The alloy may include a multiphase microstructure with an amorphous phase and nanocrystalline phase, each of the phases being ion active.
