Abstract:
A method is provided for fabricating an antimony anode. The method disperses antimony (Sb) particles in a layered carbon network using a process such as mechanical mixing, ball milling, stirring, or ultrasound sonication, forming a Sb/carbon composite. The Sb/carbon composite is mixed with a binder, forming a mixture, and the mixture is deposited on a current collector. Advantageously, the binder may be an aqueous (water soluble) binder. In one aspect, prior to dispersing the Sb particles in the layered carbon network, the Sb particles are coated with carbon. For example, the Sb particles may be dispersed in a solution including a polymer, where the solution may be an aqueous or organic. Alternatively, the Sb particles may be dispersed in a solution including a monomer. The monomer solution is polymerized to form polymer sheathed Sb core-shell structures, and then carbonized. Associated Sb anodes and Sb anode batteries are also provided.
