Nano Silicon Powder (99.99%) for Lithium-Ion Battery Anodes, 80-100 nm Primary Particle Size, High-Capacity Anode Material, ≥ 3500 mAh/g

About this item

• Ultra-High Capacity: delivers a first charge specific capacity of ≥ 3500 mAh/g with a first Coulombic efficiency of ≥ 87% (half-cell test at 0.1C), providing an ultra-high-capacity platform for next-generation lithium-ion battery anodes
• Nano Silicon Structure: primary particle size of 80-100 nm with a polycrystalline structure produced by chemical vapor deposition (CVD), supporting shortened lithium diffusion paths and enhanced rate performance
• Controlled Particle Distribution: agglomerated particle size distribution of D10 = 1.5 ± 1.0 μm, D50 = 4.0 ± 1.5 μm, and D90 ≤ 15.0 μm, facilitating electrode processing while retaining the advantages of nano-silicon
• High Purity & Low Impurities: 99.99% purity with ultra-low metal impurities (Fe ≤ 150 ppm, Ni ≤ 30 ppm, Zn ≤ 5 ppm, Co ≤ 5 ppm, Cu ≤ 5 ppm), oxygen content ≤ 2 wt%, and BET surface area of 8-16 m²/g for consistent electrochemical performance
• Material Characterization: characterized by laser diffraction particle size analysis, BET surface area measurement, scanning electron microscopy (SEM), and X-ray diffraction (XRD) to support material traceability and reproducible battery research results
