Lithium manganese iron phosphate is a mixed product of lithium iron phosphate and lithium manganese phosphate, which has the same structure as lithium iron phosphate and is an ordered and regular olivine structure. Lithium manganese iron phosphate and lithium iron phosphate have the same advantages of low cost, high safety performance, high thermal stability, no spontaneous combustion due to acupuncture and overcharge, long life, safety and no explosion risk. It can be said that it has the advantages of lithium iron phosphate and lithium manganese phosphate, and can also make up for the short board of low energy density of lithium iron phosphate, so it is also known as "the upgraded version of lithium iron phosphate".

Manganese iron lithium high voltage platform brings higher energy density, cycle, safety performance than iron lithium, low temperature performance is better than iron lithium. However, there is a low conductivity dual voltage platform manganese dissolution, resulting in industrial production is difficult, material performance and cost is difficult to take into account.

Subsidy retreat technology breakthrough, 2020 lithium iron phosphate began to return, the current business climate is still at a high level, but the iron lithium energy density is close to the upper limit, manganese iron lithium can make up for the iron lithium short board, bringing market demand. Lithium manganese iron is not a recent new material, as early as around 2014 to get market attention (when LFP is the mainstream), but the subsequent state subsidies focus on energy density, the market attitude towards LFP turned cold, so LMFP research and development gradually shelved. In 2020, lithium iron phosphate will return to the public eye. Thanks to the increased attention, the technical bottleneck of manganese iron lithium is gradually being solved.
