Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for high-purity electrochemical materials. Each batch is analyzed to confirm identity, purity, and the absence of critical metallic impurities that can affect battery performance. Certificates of Analysis (COA) detailing lot-specific results are available upon request, providing full traceability and assurance for your R&D and manufacturing processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) after opening to prevent degradation.
