Silicon-Carbon Anode Material for Lithium-Ion Batteries (Porous Carbon-Deposited Silicon), High Capacity > 1800 mAh/g, High Initial Efficiency > 90%

About this item

• Ultra-High Capacity & Efficiency: delivers a first reversible capacity of ≥ 1800 mAh/g (typical 1994.7 mAh/g at 1.5 V cutoff) with a first Coulombic efficiency of ≥ 91% (typical 92.1%), providing high energy density for next-generation lithium-ion battery anodes
• Porous Carbon-Silicon Structure: resin-based porous carbon framework (multi-hole carbon-deposited silicon) with 50% silicon content, effectively buffering volume expansion and improving structural stability during cycling
• Optimized Particle & Physical Properties: D10 ≥ 3.0 μm (typical 4.25 μm), D50 = 8.0 ± 2.0 μm (typical 8.62 μm), D90 ≤ 15.0 μm (typical 13.23 μm); BET ≤ 6.0 m²/g (typical 3.62 m²/g) and tap density ≥ 1.0 g/cm³ (typical 1.22 g/cm³), supporting slurry processability and electrode compaction
• High Purity & Low Impurities: Fe ≤ 50 ppm (typical 33.25 ppm), Cr ≤ 50 ppm (24.22 ppm), Ni ≤ 20 ppm (11.13 ppm); total magnetic impurities ≤ 1.0 ppm (typical 0.65 ppm), ensuring material safety and batch consistency
• Rate & Application Notes: delivers stable rate performance (0.2C-3C range) and cycling stability over 50 cycles at 0.1C; material should be stored under sealed conditions, and half-cell testing is recommended using carbon-coated copper foil for improved interface compatibility
