本发明涉及一种用于电池的电化学活性阴极材料。该电化学活性阴极材料包括非化学计量的β-脱锂层状氧化镍。所述非化学计量的β-脱锂层状氧化镍具有化学式。该化学式为LANiMO*nHO，其中x为约0.02至约0.20；y为约0.03至约0.20；a为约0.02至约0.2；z为约0至约0.2；n为约0至约1。在该化学式内，A为碱金属。碱金属包括钾、铷、铯及其任何组合。在该化学式内，M包括碱土金属、过渡金属、非过渡金属及其任何组合。 The invention is directed towards an electrochemically active cathode material for a battery. The electrochemically active cathode material includes a non-stoichiometric beta-delithiated layered nickel oxide. The non-stoichiometric beta-delithiated layered nickel oxide has a chemical formula. The chemical formula is LixAyNi1+a-zMzO2*nH2O where x is from about 0.02 to about 0.20; y is from about 0.03 to about 0.20; a is from about 0.02 to about 0.2; z is from about 0 to about 0.2; and n is from about 0 to about 1. Within the chemical formula, A is an alkali metal. The alkali metal includes potassium, rubidium, cesium, and any combination thereof. Within the chemical formula, M comprises an alkaline earth metal, a transition metal, a non-transition metal, and any combination thereof.
