Abstract
The invention is directed towards an electrochemically active cathode material. The electrochemically active cathode includes beta-delithiated layered nickel oxide and an electrochemically active cathode material selected from the group consisting of manganese oxide, manganese dioxide, electrolytic manganese dioxide (EMD), chemical manganese dioxide (CMD), high power electrolytic manganese dioxide (HP EMD), lambda manganese dioxide, gamma manganese dioxide, beta manganese dioxide, and mixtures thereof. The beta-delithiated layered nickel oxide has an X-ray diffraction pattern. The X-ray diffraction pattern of the beta-delithiated layered nickel oxide includes a first peak from about 14.9°2θ to about 16.0°2θ; a second peak from about 21.3°2θ to about 22.7°2θ; a third peak from about 37.1°2θ to about 37.4°2θ; a fourth peak from about 43.2°2θ to about 44.0°2θ; a fifth peak from about 59.6°2θ to about 60.6°2θ; and a sixth peak from about 65.4°2θ to about 65.9°2θ.
