Product description
Product Name: Comprehensive Selection of Sodium-ion Battery (SIB) Research Materials
Product Summary
Our Na-ion Battery Research Materials line provides the specialized, high-purity components necessary for developing next-generation sodium-ion batteries. SIBs are emerging as a compelling alternative to Li-ion technology due to the abundance and low cost of sodium, making them ideal for large-scale stationary energy storage.
We supply rigorously tested materials, including novel active compounds and high-performance auxiliary components, ensuring the controlled and reproducible fabrication of sodium-ion cell prototypes. Our focus is on materials that enable high capacity, long cycle life, and excellent rate performance essential for commercial viability.
Key Material Categories
| Category | Examples | Role in the Battery System |
| Cathode Active Materials | Na-layered oxides (e.g., NaMO₂), Prussian Blue Analogs (PBAs), Na-containing polyanions (e.g., NaV₂PO₄) | Stores and Releases Sodium Ions (Determines cell voltage and capacity). |
| Anode Active Materials | Hard Carbon, Amorphous Carbons, Sodium Titanates, Alloy Materials (e.g., Sn, Sb) | Stores and Intercalates Sodium Ions (Replaces graphite from Li-ion systems). |
| Electrolyte System | NaPF₆, NaClO₄, NaFSI salts; Solvents (e.g., PC, EC/DEC blends) | Ion Transport Medium (Allows Na⁺ ions to shuttle between the anode and cathode). |
| Auxiliary Materials | Specialized Separators, Na-compatible Binders (e.g., CMC, Lignin-based), Conductive Additives | Enables and Stabilizes Function (Maintains structural integrity, electron flow, and safety). |
