Lithium manganese iron phosphate

LiMn_0.7Fe_0.3PO₄, commonly referred to as LMFP or LMFP 70/30, is an advanced cathode material that merges the structural stability of lithium iron phosphate, LiFePO₄ or LFP, with the enhanced energy density characteristics of lithium manganese phosphate, LiMnPO₄. This olivine-structured compound features a unique blend of iron and manganese, enabling it to achieve a nominal voltage of approximately 3.8V versus lithium, compared to the 3.4V of traditional LFP. The LMFP material provides a specific capacity of about 140-150 mAh/g, which is slightly lower than that of LFP, but its higher voltage results in comparable energy density. This LMFP 70/30 is a crystalline powder that has been sieved through a 100 mesh to achieve a particle size of less than 150 µm. It is suitable for various research applications where the intrinsic properties of the cathode material are of primary interest.

Our LiFe_0.3Mn_0.7PO₄ is ideally suited for research and development of high-performance lithium-ion batteries, particularly in applications that demand enhanced safety and energy density. With a higher nominal voltage of 3.8V, LMFP serves as an excellent candidate for replacing nickel-cobalt-based cathodes, providing a cost-effective, cobalt-free alternative. The robust olivine structure and superior thermal stability of LMFP ensure safe operation across a wide range of temperatures, making it an ideal material for electric vehicles and energy storage systems. While our LMFP 70/30 provides an excellent starting point for research, it is not optimized for fast-charging applications. For improved performance in fast-charging scenarios, we recommend jet-milling the material to achieve a smaller particle size, such as 1 µm, and applying a carbon coating to the milled material. This approach can enhance the electrochemical performance and facilitate faster lithium ion diffusion, making LMFP an even more versatile option for next-generation battery technologies.
