Porous Silicon-Carbon Anode Material Si/C for Lithium-Ion Batteries – High Capacity & Long Cycle Life
Product Overview
Our Porous Silicon-Carbon Anode Material is a cutting-edge negative electrode material specifically engineered for high-performance lithium-ion batteries. Combining the high theoretical capacity of silicon with the excellent conductivity and structural stability of carbon, this porous composite material effectively solves the volume expansion issue of pure silicon anodes. With a unique porous structure, it delivers exceptional energy density, long cycle life, and superior rate capability.
Key Features
- High Energy Density: Offers a reversible capacity of 1200-1600 mAh/g, significantly higher than traditional graphite anodes (372 mAh/g), enabling batteries with larger capacity and longer runtime.
- Excellent Cycle Stability: Porous structure buffers volume expansion during lithiation/delithiation, ensuring over 1000 cycles with capacity retention rate ≥80%, reducing battery replacement frequency.
- Superior Conductivity: Carbon matrix enhances electron and ion transport efficiency, improving the rate capability of batteries—supports fast charging without sacrificing performance.
- Controlled Porosity: Tailorable porous structure (pore size: 5-50 nm) optimizes electrolyte infiltration and lithium-ion diffusion, further boosting battery performance.
- Environmentally Friendly: Manufactured via a green synthesis process with low carbon emissions, complying with global environmental standards (RoHS, REACH).
