Our anode materials are optimized as part of a full cathode-anode system. They pair with high-energy-density LFP cathodes in large-capacity cells and are engineered for long-cycle applications.
Core Process Technologies
1. High-purity graphite selection and pre-treatment
We select low-impurity graphite feedstocks and apply controlled purification and pre-treatment to minimize metallic and magnetic contaminants. Reduced side reactions during formation; lower risk of micro-shorts and lithium plating; improved consistency across large production batches; strong suitability for long-cycle applications.
2. Particle size distribution and morphology control
Tight control of PSD and particle morphology optimizes packing density and electrode uniformity. Narrow PSD for uniform current distribution; controlled spheroidization for packing efficiency; reduced electrode porosity variability; improved mechanical strength during calendaring.
3. Surface modification and interface engineering
The anode undergoes surface modification and interface optimization to stabilize the solid electrolyte interphase (SEI). Reduced irreversible capacity loss during formation; lower impedance growth over long cycling; improved high-rate performance stability; enhanced compatibility with high-power and long-duration applications.
4. Composite anode architecture (optional)
For specific applications we integrate composite formulations, combining graphite with secondary carbon phases to improve lithium-ion transport, structural resilience, rapid charge/discharge performance, and safety margins in large-format cells. Applied selectively based on customer and application requirements.
