LiFePo4 LFP Lithium Iron Phosphate Cathode Material Battery Powder

LiFePo4(LFP)​ Lithium Iron Phosphate Cathode Material Battery Powder

P198-S20 is a high-performance lithium iron phosphate (LFP) material designed for use in lithium-ion batteries. This material offers several advantages, including enhanced ion conductivity, improved capacity utilization, and excellent thermal stability. It is particularly suitable for applications requiring high safety, long cycle life, and cost-effectiveness.

Product Characteristics

P198-S20 is characterized by its unique processing techniques that enhance the performance of the LFP material:

1. ​Enhanced Ion Conductivity: Through special doping technology, the ion conductivity of the LFP material is significantly improved, enabling better capacity utilization. The specific capacity of the material at 1C discharge rate is ≥145 mAh/g, with a typical value of 145-147 mAh/g.
2. ​Particle Blending Technology: By utilizing a combination of different particle sizes, the material achieves optimal packing density. The measured tap density of the wound electrode core is 2.45-2.55 g/cm³.
3. ​Excellent Processability: Optimization of the carbon source reduces the amount of flocculent carbon between LFP particles, controlling the specific surface area to 11.0-12.0 m²/g. This improves the slurry preparation process.
4. ​High-Temperature Performance: Special dense carbon layer coating and the selection of larger particles help to block side reactions with the electrolyte, improving high-temperature cycling performance.
