The invention discloses an alkaline secondary battery cathode material [NixCuyFe2O4] and a battery using the cathode material, which belong to the technical field of the secondary battery cathode material. A main point of the technical scheme is characterized in that the secondary battery cathode material is formed by spinel-type structure ferrite [NixCuyFe2O4] or a composite material composited by the spinel-type structure ferrite [NixCuyFe2O4] and a carbon material, wherein x is less than 1 or greater than or equal to 0.5, y is less than or equal to 0.5 and greater than 0, and sum of x and yis 1. The invention also discloses a preparation method of the alkaline secondary battery cathode material and an application of the alkaline secondary battery cathode material in an alkaline secondary battery negative plate. The 0.2C discharge gram volume of the cathode material can reach 440 mAh/g, the 5C discharge gram volume can reach 350 mAh/g, and 1C volume conservation rate after circulation for 200 times can reach more than 90%, and the alkaline secondary battery prepared by the novel cathode material has the advantages of high specific energy, high specific power, and long cycle life.
