Description

Product Overview:
The Atomfair Silicon/Carbon (Si/C) Anode Electrode delivers a high specific capacity of 1100 mAh/g with a single-side areal density of 4.5 mg/cm² and an active material ratio of 90.3%. 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: 1100 mAh/g (typical), significantly exceeding conventional graphite anodes.
• Low Expansion Design: Silicon-carbon composite structure limits volume change to <30% during cycling.
• Controlled Areal Density: 4.5 mg/cm² (single-side coating) with 90.3% active material content for high reproducibility.
• Standardized Packaging: 5 sheets per pack, minimizing handling and contamination risks.
• Long Cycle Life: >80% capacity retention after 2000 cycles (0.5C rate).
