Electroless Deposition Method for Producing Metallic Films and Their Alloys

Research is active on the patent-pending technology titled, “Electroless Deposition of Bi, Sb, Si, Sn, and Co and Their Alloys.” This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
Abstract: 
Technologies ranging from cell phones to the electric grid all use batteries to harness, store, and deliver energy. Batteries contain an anode and a cathode, and the anode requires amorphous, porous, or nanocrystalline thin films of metal and their alloys to provide a high reversible capacity and excellent columbic efficiency—key factors in high battery performance and long battery life. This invention describes a method of creating these thin films of metal and their alloys by direct electroless deposition. This technique uses several simple aqueous or non-aqueous based chemical baths with some complexing agents. This simple method can easily be extended to industrial-scale deposition and fabrication in bulk on a variety of conducting substrates, which will allow for application in battery technology. Multiple layers of various metals and their alloys can be created in any desired order or thickness.
