Key Functional Benefits

Why Spherical Graphite Matters in ESS

Spherical graphite is the preferred anode material for lithium-ion batteries used in ESS applications due to its optimized particle morphology, purity, and electrochemical stability.

Long cycle life for daily charge–discharge use
Stable performance over extended operating periods
Improved electrode packing and tap density
High first-cycle efficiency with lower formation losses
Thermal and structural stability during continuous operation

Key Material Characteristics

Energy storage systems require battery materials engineered for long-duration cycling, thermal stability, and predictable performance across thousands of charge–discharge cycles.

Ultra-high purity (≥99.95% carbon)
Controlled particle size distribution (D50 ~10–25 µm)
Low metallic impurities (Fe, Si, Ca at ppm levels)
Optimized tap density for durable electrode structures
Exceptional long-term cycling stability
