  • Electrode material
    Patent number: 4497726
    Abstract: A cathode active material, which is especially useful as the cathode in a lithium high energy density nonaqueous cell operating on the principle of intercalation, has the general formula Li.sub.x M.sub.y M'.sub.z O.sub.2-n F.sub.n where M is selected from the group consisting of metallic ions having a valence of +1 other than lithium and metallic radicals having a valence of +1; M' is selected from the group consisting of Fe, Co and Ni; x is 0.01 to 0.99 and y is 0.99 to 0.01, respectively; z is 0.8 to 1.2; and n is zero to 0.1.
