Cathode material for lithium ion battery - lithium manganese iron phosphate (LMFP)
-
Product Details
The theoretical capacity of lithium manganese iron phosphate is the same as that of lithium iron phosphate, which is 170mAh / g, but its electrode potential relative to Li + / Li is 4.1V, much higher than that of lithium iron phosphate, which is located in the stable electrochemical window of the organic electrolyte system. The high potential of 4.1V makes lithium manganese iron phosphate have the advantage of potential high energy density, which is its biggest advantage over lithium iron phosphate.
The actual capacity of lithium ferromanganese phosphate is the same as that of lithium iron phosphate, and its energy density will be 15% higher than that of lithium iron phosphate. Compared with lithium manganate with equivalent voltage, its mass energy density can also be increased by more than 25%. In addition, lithium manganese iron phosphate has low raw material cost, friendly environment and broad market prospect.Physical indexes Item Unit Specification Typical value Appearance / Black powder / Tamping density g/cm3 ≥0.7 0.78 Specific surface area m2/g 20±5 20.00 H2O ppm ≤1000 700 D10 μm ≥0.3 0.34 D50 μm 1.0±0.5 0.86 D90 μm ≤15.00 8.50 Electrochemical performance First time efficiency % ≥90 93.3 Chemical indexes Li % 4.4±0.3 4.3 Mn % 19.0~21.0 19.8 Fe % 13.0~14.5 13.6 P % 19.5±1.0 19.2 C % 2.0±0.5 2.0 Na ppm ＜500 200 Ca ppm ＜200 130 Ni ppm ＜200 45 Zn ppm ＜50 38 Cr ppm ＜50 15 Cu ppm ＜50 10 pH / 9~11 11.65 Magnetic foreign matter (Fe + Cr + Zn) ppb ≤50 15 SEM
