Ossila lithium manganese iron phosphate (LMFP) powder, CAS 1354700-46-1, is a cathode active material for lithium batteries with the formula LiMn0.6Fe0.4PO4. It is a manganese-doped form of lithium iron phosphate (LFP), supplied as a black/brown powder with a D50 particle size of 1.01 μm.
Adding manganese raises the working voltage of the cell through the Mn2+/3+ redox couple (~4.1 V), giving an energy density of 210-240 Wh/kg, higher than that of standard LFP cells. The material shows a capacity of 161.3 mAh/g at 0.1C, a rate capability of 90.1 mAh/g at 5C, and retains 95.6% of its capacity after 800 cycles at 1C.
LMFP adopts an olivine-type structure in which tetrahedral phosphate units form a rigid framework that resists lattice distortion, supporting structural stability and safety during charge and discharge. The manganese ratio matters: above 60 wt% manganese, Jahn-Teller distortion of Mn3+ slows redox kinetics and causes anisotropic lattice strain, lowering rate performance and volumetric capacity. The powder is described as having low water and carbon content.
