Quality Control

Our Lithium Hexafluorophosphate is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity, critical for optimal battery performance and safety. Production adheres to relevant industry standards, with rigorous testing for key impurities such as moisture, HF content, and metallic ions. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the product must be handled and stored under a dry, inert atmosphere (e.g., argon or nitrogen) to prevent decomposition. Recommended long-term storage temperature is 2-8°C. Keep away from strong bases and incompatible materials.
