Packaging, Storage & Handling Instructions

• Packaging: Vacuum-sealed or dry-inert sealed inside moisture-barrier aluminum-laminate bags.

• Storage Conditions: Store in a cool, dry, and tightly sealed environment. Protect strictly from moisture, contamination, heat sources, ignition points, and strong oxidizers.

• Handling Note After Opening: Because the material is moisture-sensitive, handle promptly in a dry room, low-humidity environment, or inert gas glovebox, and reseal immediately after use.

Disclaimer: Electrochemical performance is protocol-dependent. Specifications listed represent standard reference benchmarks and batch-specific Certificate of Analysis (COA) data supersedes typical representative metrics.
