Quality Control

Our Lithium Difluorophosphate is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and moisture content determination, to ensure it meets exacting specifications for high-performance applications. Certificates of Analysis (COA) are provided with every shipment to guarantee traceability and batch-to-batch consistency.

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). This material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere (e.g., argon or nitrogen) to prevent decomposition.
