To provide an electrochemically active cathode material which has improved discharge performance and low closed circuit voltages, is low in gas evolution, and includes beta-delithiated layered nickel oxide.SOLUTION: There is provided an electrochemically active cathode material including beta-delithiated layered nickel oxide. The beta-delithiated layered nickel oxide has an X-ray diffraction pattern including: a first peak (111) from about 14.9°2θ to about 16.0°2θ; a second peak (112) from about 21.3°2θ to about 22.7°2θ; a third peak (113) from about 37.1°2θ to about 37.4°2θ; a fourth peak (114) from about 43.2°2θ to about 44.0°2θ; a fifth peak (115) from about 59.6°2θ to about 60.6°2θ; and a sixth peak (116) from about 65.4°2θ to about 65.9°2θ.SELECTED DRAWING: Figure 2 【課題】向上した放電性能、低い閉路電圧を有し、ガス発生の低い、ベータ脱リチウム化層状酸化ニッケルを備える電気化学的に活性なカソード材料の提供。【解決手段】約１４．９°２θから約１６．０°２θの第１ピーク（１１１）、約２１．３°２θから約２２．７°２θの第２ピーク（１１２）、約３７．１°２θから約３７．４°２θの第３ピーク（１１３）、約４３．２°２θから約４４．０°２θの第４ピーク（１１４）、約５９．６°２θから約６０．６°２θの第５ピーク（１１５）、及び約６５．４°２θから約６５．９°２θの第６ピーク（１１６）を含んでいる、ベータ脱リチウム化層状酸化ニッケルを備える電気化学的に活性なカソード材料。【選択図】図２
