The invention belongs to the technical field of battery materials, and discloses a cobalt iron-nitrogen heterocarbon material catalyst, preparation method and application in battery, especially in zinc-air battery. The preparation method of the invention adopts a microwave reduction method to synthesize, comprising the following steps: adding carbon material into an alcohol solution of cobalt saltand iron salt to obtain a mixed solution of metal salt mesoporous carbon; The alkali and reducing agent are dissolved in water, added dropwise into the mixed solution, dispersed by ultrasonic wave, reduced by microwave, filtered and washed to obtain cobalt iron-Nitrogen heterocarbon material catalyst. The invention also provides the cobalt iron obtained by the above method. Nitrogen heterocarbonmaterial catalyst, which has high specific surface area, CoFe alloy and nitrogen heterocarbon material have strong synergistic effect, have good battery charging and discharging performance, so it canbe used as high-performance cathode material of zinc-air battery, so it can be used in batteries, especially in zinc-air batteries.
