About Natural graphiteI Negative electrode material(High Grade) Data
It is based on domestic Chinese market prices.
Natural Graphite
Raw Materials: Natural graphite mined from deposits (flake graphite)
Manufacturing Process: Removal of impurities (purification), spheroidization, and surface coating
Advantages: High initial capacity and low cost due to low power consumption during manufacturing
Disadvantages: Faster degradation (expansion) due to repeated charge-discharge cycles, resulting in a shorter service life
GradesGrades are primarily classified based on specifications such as energy density (discharge capacity), cycle life, and rapid-charging performance.
High-Grade
This is the top-tier grade that balances high capacity, approaching the theoretical limit of graphite, with the stability to withstand rigorous usage.
- Target Discharge Capacity:
350–360 mAh/g or higher - Main Applications:
Premium EVs (long-range models), rapid-charging compatible EVs, and high-end smartphones. Technical Features:
Secondary Granulation Technology: By aggregating multiple fine particles and creating gaps within them, lithium-ion transport is smoothed, dramatically enhancing rapid-charging performance.Advanced Surface Coating: Uniform coating with specialized pitch or carbon layers minimizes side reactions with the electrolyte, significantly extending service life.
