Lithium Battery Cathode Material Lithium Iron Phosphate LiFePO4 Powder LFP

Product Overview

This high-purity lithium iron phosphate (LiFePO4/LFP) powder serves as an advanced cathode active material engineered specifically for high-safety, long-cycle-life lithium-ion battery development and manufacturing. Combining superior olivine-structure stability with an optimized conductive carbon surface coating, the material delivers balanced electrochemical performance, robust power delivery, and exceptional environmental safety across demanding operating regimes.

Designed for electrochemical laboratories, pilot fabrication facilities, and commercial cell production, this cathode powder is widely utilized in electric vehicle (EV) cells, stationary energy storage systems (ESS), and high-rate power tools. Compared to traditional layered transition metal oxides (such as LiCoO2 and Ni-rich NMC) or spinel structures (such as LiMn2O4), this material eliminates cobalt dependency, mitigates toxic transition metal leaching, and provides outstanding thermal stability under abusive operating conditions.

The powder undergoes rigorous multi-stage quality control to guarantee tight particle size distribution, minimal trace metal contaminants, and exceptionally low residual moisture content. Shipped vacuum-sealed and ready for direct slurry integration without pre-drying, this cathode material ensures reproducible coating rheology, superior electrode adhesion, and dependable electrochemical yields across coin cell, pouch cell, and cylindrical cell formats.

Key Features

• Superior First-Cycle Efficiency and Discharge Capacity: Delivers high initial discharge capacities (≥150.0 mAh/g at 0.1C) with a first-cycle Coulombic efficiency exceeding 95%, ensuring optimal energy retention during full-cell formation.
• Nanostructured Carbon Coating for Enhanced Conductivity: Features an engineered surface carbon layer (1.0% to 1.5% C content) that overcomes intrinsic olivine conductivity limitations, facilitating rapid lithium-ion diffusion and lowering bulk electronic resistivity (≤100 Ω·cm).
• Precision Particle Size Engineering: Formulated with tightly controlled particle distributions (D50 ranging from 0.6 µm to 4.0 µm across specialized variants) to maximize slurry packing density, prevent agglomeration, and achieve uniform doctor-blade coating.
• Ultra-Low Moisture Content for Direct Slurry Processing: Strictly controlled to <1000 ppm via Karl Fischer coulometry at 200°C, eliminating the requirement for secondary vacuum baking and mitigating electrolyte hydrolysis and hydrofluoric acid generation.
• High Tap Density and Packing Homogeneity: Optimized morphology provides tap densities up to 1.0 ± 0.2 g/cm³, allowing researchers and cell manufacturers to fabricate high-calendering-density electrodes without particulate fracture.
• Stringent Metal Impurity Control: Utilizing high-precision ICP-OES validation, transition metal and alkali impurities (Ca, Na, Mg, Cr, Mn, Ni, Cu, Zn) are restricted to ppm-level thresholds to prevent internal micro-shorting and localized self-discharge.
• Intrinsic Thermal and Chemical Resilience: Exhibits exceptional resistance to thermal runaway up to temperatures exceeding 600°C, offering superior operational tolerance compared to standard layered oxide cathodes.
• Consistent Microstructural Uniformity: Uniform sub-micron primary particles and spherical or quasi-spherical secondary aggregates maintain long-term structural integrity through extensive lithiation and delithiation cycles.
