Overview | Product Information | Crystal Structure | MSDS | Related Products

Lithium manganese iron phosphate, LMFP (CAS number 1354700-46-1), is a cathode material for lithium batteries, also known as a manganese doped variant of lithium iron phosphate (LFP). The doping of manganese in lithium manganese iron phosphate increases the operating voltage of battery cells, yielding greater energy density (210-240 Wh/kg), compared to standard LFP battery cells. LMFP also delivers excellent electrochemical performance, exhibiting a capacity of 161.3 mAh/g at 0.1C, a rate capability of 90.1 mAh/g at 5C, and good cycling stability of 95.6% capacity retention after 800 cycles at 1C.

The doping ratio of manganese is crucial in lithium manganese iron phosphate. With more than 60 wt% manganese content, sluggish Mn^2+/3+ redox kinetics occur, caused by Jahn-Teller distortion of Mn³⁺. This results in significant anisotropic lattice strain, leading to lower rate performance and volumetric capacity.

Crystal Structure

LMFP has an olivine-type structure, where the phosphate ions form stable tetrahedral units that support the charge-discharge process. This rigid tetrahedral framework enhances the mechanical integrity of the lattice by resisting distortion. Manganese doping raises the operating voltage by introducing the Mn^2+/3+ redox couple (~4.1 V), which increases energy density. It also improves structural stability and safety while maintaining cost-effectiveness and high performance.
