Quality Control

Our Lithium Manganese Dioxide is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and high performance in downstream applications. Quality parameters are strictly controlled, including purity, particle size distribution (PSD), tap density, and specific surface area (BET). A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place under controlled humidity conditions, ideally in a desiccator or under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and moisture absorption. Recommended storage temperature is 15-25°C in a well-ventilated area separate from incompatible materials.
