Product Description
Lithium ion Battery Cathode Material Lithium Iron Manganese Phosphate LFMP LMFP Powder LiMnFePo4
The theoretical capacity of lithium iron manganese phosphate is 170mAh/g, which is the same as that of lithium iron phosphate, but its electrode potential relative to Li+/Li is 4.1V, which is much higher than the 3.4V of lithium iron phosphate, and it is located in the stable electricity of the organic electrolyte system. Chemistry window. The high potential of 4.1V gives lithium iron manganese phosphate the potential advantage of high energy density, which is the biggest advantage over lithium iron phosphate. In addition, the raw material cost of lithium iron manganese phosphate is low, environmentally friendly, and the material has a broad market prospect.
1.Lithium iron manganese phosphate LMFP cathode material solves the shortcomings of poor circulation of manganese-based cathode
materials, so that it maintains the characteristics of excellent cycling performance of phosphate cathode materials.
2.The material also solves the shortcomings of poor high-temperature performance of manganese-based materials, showing excellent
high-temperature performance, the capacity is greatly improved at high temperatures, and the cycle performance is basically not
affected;
3.The mixed use of LMFP material and ternary material can improve the stability and safety of the ternary material under high
voltage, and improve the capacity and safety of the ternary power battery.
