This program will lead to advanced high energy density battery materials that will generate more power than presently used materials and thus, greatly improve existing battery technology. Powder will be produced through a novel combustion process that couples industry-standard chemistry with a proven industrial powder production system. This process yields nanoparticles that are coated with sodium chloride, which serves as a protective barrier for safe handling and storage in air. Prior to implementation into batteries, sodium chloride will be removed, powder will be sintered into anode pellets, and the anodes will be coated with electrolyte, in such a way that the material is never exposed to oxygen, thus maximizing performance of the particles. During Phase I, to demonstrate feasibility, titanium diboride nanoparticles will be produced, processed, and battery performance will be tested in laboratory tests. In addition to demonstrating the improved performance of battery materials, the program will enable production of a broad range of technologically important materials because the production and processing technologies are generic and will thus enhance the leadership role of the U.S. in advanced materials. Anticipated Benefits/Commercial Applications: This program will produce a new class of advanced batteries by exploiting the unique properties of high purity matal and ceramic nanopowders. A low-cost domestic source of high purity, low oxygen nanoparticles will open up many markets in advanced battery technologies, both in the U.S. military and in commercial applications. Furthermore, the generic technology enables production of a broad range of nanomaterials and opens up many markets in the automotive, biomedical, defense, electronics, and other industries. Both the U.S. military and commercial sector are demanding substantial advances in such technologies and the proposed materials offer a realistic scenario for achieving these goals.
