4.1V High Voltage LMFP Cathode Powder for Next-Gen EV Batteries – Enhanced Energy Density
Product Overview
LMFP represents the evolution of Lithium Iron Phosphate (LFP) technology. By optimizing the Manganese-to-Iron ratio, our LMFP material combines the safety and low cost of LFP with the high voltage of Manganese-based chemistries. It is specifically designed for battery manufacturers seeking to bridge the gap between LFP and NCM performance.
Technical Highlights
-
High Operating Voltage: A distinct voltage plateau at 4.1V compared to LFP’s 3.4V.
-
Enhanced Energy Density: Delivers significantly watt-hours per kilogram (Wh/kg).
-
Superior Low-Temp Performance: Better capacity retention in cold climates compared to standard LFP.
-
Safety & Stability: Retains the stable olivine structure, ensuring high thermal runaway temperatures and long cycle life.
Parameters Specifications Specific Capacity (0.1C) ≥ 155 mAh/g First Efficiency ≥ 90% Average Voltage ~4.1 V Tap Density ≥ 1.0 g/cm³ D50 Particle Size 2.5 – 4.5 μm
