Material Characteristics:

  1. High Capacity
    Through specialized doping technology, the ionic conductivity of the LFP material is effectively enhanced, significantly improving the utilization of the material’s specific capacity. Full cell 1C capacity >145 mAh/g, typical values range from 145 to 147 mAh/g.
  2. Excellent Processability
    By optimizing the carbon source, the amount of flocculent carbon between LFP particles is reduced, controlling the material’s median specific surface area between 11.0 and 12.0 m²/g, effectively improving the slurry preparation process.
  3. High Tap Density
    Using a particle mixing technology that leverages the advantages of different particle sizes to achieve better packing of LFP particles, resulting in improved tap density. The tested wound cells achieve a compaction density of 2.45–55 g/cm³.
  4. Outstanding High-Temperature Performance
    Special dense carbon coating technology and selection of large particle ratios help to block electrolyte side reactions and reduce reactive interface areas, contributing to improved cycling performance at high temperatures.
