LMFP is an improved phosphate cathode material with the chemical structure of LiFe₁₋ₓMnₓPO₄. It is a solid solution formed by introducing manganese (Mn) elements on the basis of traditional LFP (lithium iron phosphate). Its purpose is to enhance the energy density and working voltage while retaining the high safety and long life advantages of LFP, and is considered one of the next-generation high-performance and cost-effective power and energy storage battery materials.
