Silicon-Carbon Alloy (950)-B

This product is developed as a high-capacity anode material for lithium-ion batteries, specifically designed to enhance energy density in advanced energy storage systems. The silicon-carbon alloy 950 features a controlled particle size distribution (D50 around 10.3 µm) and a moderate BET specific surface area of 1.36 m²/g, balancing reactivity with processability. With an initial reversible capacity exceeding 905 mAh/g and a first-cycle coulombic efficiency of approximately 82.7%, it offers improved electrochemical performance compared to conventional graphite anodes. Typical applications include high-energy-density battery cells for electric vehicles and portable electronics, where higher capacity electrodes are critical for extending runtime or range. The material’s tap density of 0.84 g/cm³ and low moisture content support consistent electrode preparation and slurry processing.

Storage Requirement: Materials must be stored in a sealed container.
