Battery Cathode Material Lithium Manganese Iron Phosphate LMFP Powder

Product Overview

This high-purity lithium manganese iron phosphate (LMFP) cathode powder represents an advanced evolution in olivine-structured energy storage chemistry. By incorporating manganese into the iron phosphate crystal lattice, this material elevates the operating voltage plateau to 4.1 V versus lithium, unlocking higher energy density while retaining the intrinsic thermal and structural safety of traditional phosphate materials. It provides electrochemical cell designers and materials scientists with an optimized balance of energy output, cycle life, and thermal resilience.

Engineered specifically for next-generation lithium-ion battery research, pilot prototyping, and high-performance commercial production, this material serves electric mobility, stationary energy storage systems (ESS), and specialty industrial power applications. Its controlled sub-micron core morphology facilitates rapid lithium-ion diffusion pathways, making it especially effective for high-rate discharge demands and low-temperature operating environments.

Manufactured under rigorous quality control standards, this cathode powder ensures outstanding batch-to-batch consistency, low internal moisture, and optimized carbon network conductivity. Whether evaluated in coin half-cells, multi-layer pouch configurations, or wound cylindrical formats, the material delivers dependable coulombic efficiency and long-term cycling stability under demanding electrochemical and thermal stress.

Key Features

• Elevated Operating Voltage Plateau: Manganese incorporation shifts the operating voltage profile upward toward a 4.1 V plateau, significantly boosting volumetric and gravimetric energy density compared to conventional standard lithium iron phosphate chemistries.
• High Initial Discharge Capacity: Delivers a 0.2C first discharge capacity of 154.4 mAh/g with an initial coulombic efficiency of 93.26%, maximizing active material utilization right from the formation cycle.
• Engineered Sub-Micron Primary Particle Size: Characterized by a tight particle size distribution with D10 of 0.327 µm, D50 of 0.936 µm, and D90 of 14.786 µm, shortening solid-state lithium-ion diffusion lengths for enhanced rate capability.
• Optimized Carbon Network Coating: Features an integrated 1.88% carbon content providing uniform surface conductivity, compensating for the low intrinsic electrical conductivity of pristine phosphate crystals without compromising packing density.
• Controlled Surface Area for Stable Slurry Processing: A measured specific surface area of 19.34 m²/g provides an ideal interfacial contact area with liquid or solid electrolytes while maintaining manageable slurry viscosity during electrode coating operations.
• Rigorous Moisture Suppression: Maintained at a strict moisture limit of 599.2 ppm to prevent hydrofluoric acid generation in liquid electrolytes and avoid interfacial degradation in advanced battery systems.
• Precise Stoichiometric Transition Metal Balance: Formulated with an accurate elemental distribution including 4.3% Lithium, 20.83% Manganese, 13.96% Iron, and 19.01% Phosphorus to maintain long-range olivine crystal integrity throughout prolonged lithiation-delithiation cycling.
• Enhanced Structural and Thermal Stability: Retains strong covalent P-O bonding within the crystalline framework, preventing oxygen release during high-temperature abuse or severe overcharge conditions.
