In the current field of power batteries, the mainstream application materials are olivine structure of lithium iron phosphate and layered ternary nickel cobalt manganese material (NCM), and lithium manganese iron phosphate as a positive development material based on lithium iron phosphate, its performance compared to the two have advantages and disadvantages.

Compared with lithium iron phosphate, the high voltage characteristic of manganese enables lithium manganese iron phosphate to have a higher voltage platform, which also leads to a higher energy density when the specific capacity is the same, and the energy density is 10%-20% higher than that of lithium iron phosphate under the same conditions, but the disadvantage is that the introduction of manganese significantly reduces the conductivity of the material. At the same time, a higher voltage platform also means higher requirements for electrolytes, and relatively few types of electrolytes meet the discharge characteristics.

Compared with the layered structure of the ternary NCM material, lithium manganese iron phosphate has the same olivine structure as lithium iron phosphate, and the structure is more stable during charging and discharging, and even if all lithium ions are embedded during charging, the structure will not collapse, so it is safer and has a lower cost. The disadvantage is that compared with efficient ternary materials, the specific capacity and energy density of lithium manganese iron phosphate are still very low, and the gap in conductivity is even greater. This has also led to the current application of lithium manganese iron phosphate in small power fields such as electric two-wheeled vehicles with relatively low performance requirements.
