Abstract: An electrode for a rechargeable lithium-ion battery is formed by mixing stanous oxide (SnO) and lithium nitride (Li3N) in a stoichiometric ratio of 2 moles of Li3N to 3 moles of SnO to form a mixture, milling the mixture to obtain a milled powder, and processing the milled powder in accordance with an electrode-forming technique. The electrode forming technique can be any one of die pressing, spraying, doctor-blading and rolling. Conductive additives, such as carbon and binders (PVDF, cellulose and Teflon), can be introduced during the processing step. Preferably, the method is carried out in a dry, inert atmosphere of argon or helium. As a result of the invention, a smaller, lighter and more efficient lithium-ion battery is produced.
