Quality Control

Our Lithium Difluoro(Oxalato)Borate(1-) is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity, meeting the exacting requirements of the battery industry. All materials are supported by comprehensive analytical data. Certificates of Analysis (COA) detailing purity, moisture content, and key impurity profiles are available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material must be stored in a cool, dry place under an inert atmosphere (e.g., argon or nitrogen) to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability. Handle and open containers only in a controlled, dry environment.
