Lithium Iron Phosphate Cathode Active Material

Product Specifications

Technical details and manufacturing context for Lithium Iron Phosphate Cathode Active Material

Definition

Lithium iron phosphate (LiFePO4) cathode active material is a critical raw material in battery manufacturing, serving as the positive electrode component in lithium-ion cells. This olivine-structured compound provides superior thermal stability and safety compared to other cathode chemistries, making it essential for electric vehicles, energy storage systems, and industrial applications. As a semi-finished industrial substance, it's supplied to battery manufacturers as a fine powder that undergoes electrode slurry preparation, coating, and calendaring processes. Its role in the B2B supply chain involves specialized chemical producers supplying to cell manufacturers who integrate it into complete battery systems. The material is characterized by a specific capacity of 140–160 mAh/g, a tap density of 0.8–1.2 g/cm³, a particle size D50 of 1–5 μm, a BET surface area of 10–20 m²/g, a carbon content of 1–3 wt%, a moisture content of ≤0.1 ppm, an operating voltage of 2.5–3.65 V, a charge/discharge efficiency of ≥95%, a compaction density of 2.2–2.5 g/cm³ under 10 MPa, a pH value of 9–11, and an impurity content (Fe, Cu, Zn) of ≤0.01%. These parameters serve as reference ranges for procurement and quality control; actual values must be confirmed with the supplier for the specific grade. The material is supplied as a powder and is not a finished battery component. Buyers should verify that the material meets their application requirements, including electrochemical performance and processing characteristics. The directory does not manufacture or sell this product; it provides neutral technical information for industrial sourcing.

Working Principle

The material operates through reversible lithium-ion intercalation/de-intercalation within the olivine crystal structure during charge/discharge cycles. During discharge, lithium ions are extracted from the anode and inserted into the iron phosphate lattice, while electrons flow through the external circuit. This process is reversed during charging. The olivine structure provides a stable framework that accommodates lithium ions without significant structural change, contributing to the material's thermal stability and long cycle life. The carbon coating enhances electronic conductivity, facilitating efficient electron transfer. The operating voltage window of 2.5–3.65 V is typical for LiFePO4, and the theoretical capacity is approached under optimal conditions. The material's performance is influenced by particle size, surface area, and impurity levels, which affect kinetics and side reactions.

Frequently Asked Questions

What is the typical specific capacity of this material?

The specific capacity is typically in the range of 140–160 mAh/g, based on theoretical electrochemical capacity at 100% utilization. Actual capacity depends on the specific grade and test conditions; verify with the supplier.

What is the recommended particle size for electrode processing?

The median particle diameter (D50) is typically 1–5 μm. This range is suitable for slurry preparation and coating. Confirm the exact distribution with the supplier for your application.

How does the carbon content affect performance?

The carbon content, typically 1–3 wt%, provides a conductive coating that enhances electronic conductivity. Higher carbon can improve rate capability but may reduce energy density. Verify the optimal level for your battery design.

What are the key quality parameters to verify before procurement?

Key parameters include specific capacity, tap density, particle size, BET surface area, carbon content, moisture content, operating voltage, charge/discharge efficiency, compaction density, pH, and impurity content. Always confirm these values with the manufacturer for the specific batch.
