LMFP v. LFP STRUCTURE
LMFP partially replaces Fe in LFP with Mn.
Incorporating Mn into the system raises the redox voltage, resulting in increased overall energy density. PERFORMANCE
LMFP’s capacity at low-temperature performance is more stable compared to LFP.
Both chemistries exhibit similar safety profiles. MARKET/ USAGE
LMFP-64 (60% Mn content) is the most widely available composition in the market, with research efforts now shifting towards 70% Mn content.
LMFP is often blended with NMC due to its similar voltage, which improves the safety and reduces the cost relative to NMC.
