About Natural graphite Negative electrode material(Low 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.
Low-Grade (Low-End)
This grade is designed for maximum cost efficiency by simplifying the manufacturing process.
- Target Discharge Capacity: Approximately 310–330 mAh/g
- Main Applications: E-bikes, small home appliances, and cost-sensitive stationary energy storage systems (ESS).
- Technical Features: For artificial graphite, production costs (electricity expenses) are reduced by lowering the firing temperature (compromising the degree of graphitization). Due to slightly greater variation in particle size and simpler surface treatment, it is not suitable for rapid charging and has a relatively shorter cycle life.
