Abstract
Cathode active materials that include a metal compound having the formula MR, where M is a metal, R is an atom, a molecule, or a radical having an oxidation state of −1, and x is a positive nonzero real number; and a metal oxide having the formula M'O, where M′ is a metal, and y and z are independently positive nonzero real numbers; provided that the metal compound and the metal oxide are in contact. The cathode active materials can be used to prepare cathodes that evolve little or no oxygen during operation. The cathodes can be economically incorporated into batteries that can provide high energy density.
