The invention is directed towards an electrochemically active cathode material. The electrochemically active cathode includes beta-delithiated layered nickel oxide. 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. L'invention concerne un matériau de cathode électrochimiquement active. La cathode électrochimiquement active comprend de l'oxyde de nickel stratifié bêta-délithié. L'oxyde de nickel stratifié bêta-délithié possède un diagramme de diffraction des rayons X. Le diagramme de diffraction des rayons X de l'oxyde de nickel stratifié bêta-délithié comprend un premier pic d'environ 14,9° 2θ à environ 16,0° 2θ; un deuxième pic d'environ 21,3° 2θ à environ 22,7° 2θ; un troisième pic d'environ 37,1° 2θ à environ 37,4° 2θ; un quatrième pic d'environ 43,2° 2θ à environ 44,0° 2θ; un cinquième pic d'environ 59,6° 2θ à environ 60,6° 2θ; et un sixième pic d'environ 65,4° 2θ à environ 65,9° 2θ.
