Abstract
A manganese iron oxide and a preparation method thereof, and a preparation method for lithium manganese iron phosphate cathode materials are provided. The preparation method for the manganese iron oxide includes the following steps: Configuring a mixed salt solution containing the first complexing agent, antioxidant, manganese salt, and iron salt; mixing the mixed salt solution, the second complexing agent, oxidant and deionized water to undergo a complexation-oxidation-precipitation reaction, filtering, washing, and drying a precipitate obtained after the reaction to obtain a manganese iron oxide. The preparation methods for the manganese iron oxide and lithium manganese iron phosphate cathode materials are simple, the physical and chemical indexes of the product are controllable, the raw materials are easy to obtain, the cost is low, the reaction conditions are mild, the corrosion resistance requirements of the equipment are not high, the technical difficulty is low, and it is easy to scale production.
