Description

Product Overview:
The Atomfair Silicon/Carbon (Si/C) Anode Electrode delivers a high specific capacity of 1350 mAh/g with a fixed compaction density of 1.0 g/cc, ultra-thin 6μm copper foil current collector, and optimized 5.5 mg/cm² areal density at 90.2% active material ratio. Each pack contains 5 pre-cut electrodes, ensuring consistency and convenience for experimental use. Engineered for minimal volume expansion and extended cycling performance, this electrode is ideal for high-energy-density lithium-ion battery research and development.

Key Features:

• High Specific Capacity: 1350 mAh/g (typical), significantly exceeding conventional graphite anodes.
• Low Expansion Design: Silicon-carbon composite structure limits volume change to <30% during cycling.
• Optimized Compaction: Fixed 1.0 g/cc density balances porosity and ionic/electronic conductivity.
• Controlled Areal Density: 5.5 mg/cm² (single-side coating) with 90.2% active material content for high reproducibility.
• Ultra-Thin Current Collector: 6μm copper foil reduces inactive weight and enhances energy density.
• Standardized Packaging: 5 sheets per pack, minimizing handling and contamination risks.
• Long Cycle Life: >80% capacity retention after 500 cycles (0.5C rate).
