Lithium manganese iron phosphate is a new type of phosphate lithium-ion battery cathode material formed by doping a certain proportion of manganese on the basis of lithium iron phosphate. Through the doping of manganese, the advantages of iron and manganese can be effectively combined. At the same time, manganese and iron are located in the fourth period subgroup and adjacent in the periodic table, with similar ionic radius and some chemical properties, so doping will not significantly affect the original structure.
The preparation methods of lithium manganese iron phosphate can be divided into two categories: solid phase method and liquid phase method. Specifically, the solid phase method includes high-temperature solid phase method, carbothermic method, etc. The process of this method is simple and mature, the preparation cost is low, and it is easy to achieve large-scale industrialization. The liquid phase method includes solvent thermal method, sol-gel method, co-precipitation method, etc. This method has good tolerance to raw materials and high product quality. For details, please see the table below.
| Preparation method | Preparation process | Characteristics |
| High-temperature solid phase method | The divalent iron salt and other raw materials are mechanically milled or high-energy ball milled to crush and mix the materials to obtain the precursor. Then the finished product is obtained by high temperature calcination and grinding. | The cyclic performance is good, but the rate performance and electrochemical performance are poor. |
| Carbothermic method | First, the low-cost trivalent iron salt is reduced to divalent iron salt under the action of carbon as an iron source. Then the divalent iron salt is mixed with other raw materials and ball-milled to obtain a precursor. Finally, calcination and grinding are performed to obtain the finished product. | Good conductivity and stability, and low raw material cost. |
| Solvent thermal method | First, the raw materials are dissolved in a solvent to form a uniform solution, and then reacted in a reactor to obtain a precursor. Finally, the finished product is obtained by drying and roasting. | Good stability, but poor bulk density and compaction density. |
| Sol-gel method | The raw materials are dissolved in a solvent, stirred or ball-milled to obtain a uniform sol, and then the temperature is increased to gel the system to obtain a wet gel. Finally, the finished product is obtained by drying, dehydration, and roasting. | The product has excellent performance in many aspects, but the operation is cumbersome. |
| Co-precipitation method | Various raw materials are dissolved in a solvent, and then a coprecipitant is added to obtain a precipitate. Subsequently, the precursor is obtained by centrifugal separation. Finally, the finished product is obtained by washing, drying and roasting. | The product has excellent performance in many aspects and uniform particle distribution. |
