Abstract
Described are cathode materials for lithium batteries. Better cathode materials may be produced by mixing at least two compounds and a binder additive. The first compound includes one or more salts of lithium metal phosphorous while the second compound includes one or more lithium transition metal oxides. In other instances, a conductive additive may also be incorporated. The cathode materials so produced exhibit enhanced electrical properties and thermal stability.
