Quality Control

Our Lithium Difluorophosphate is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, moisture content, and impurity profiles. We adhere to relevant industry standards and can provide material tailored to specific customer requirements for battery-grade or research-grade applications.

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 container must be kept sealed under an inert atmosphere (e.g., argon or nitrogen) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
