Recommended Handling:
Single-crystal Ni83 NCM should be handled in a dry environment (relative humidity preferably below 30%, dew point below −40°C recommended) to minimize moisture pickup and surface Li-residue increase. Store in a sealed container in a cool, dry place away from acidic vapors and reducing atmospheres. For slurry preparation, use NMP solvent with PVDF binder (e.g., Solef-class) and follow standard cathode-slurry formulation protocols (active material + conductive carbon + binder). Coat onto aluminum current collector using a film coater (e.g., XN-VC-300, XN-VCH-300, XN-SDC) followed by drying and calendering (e.g., XN-CRPE or XN-HRPE roller press series). High-nickel cathodes are more moisture-sensitive than medium-nickel NCM — open inner moisture-barrier packaging only inside a controlled-atmosphere environment whenever possible.
Packaging & Storage:
Standard packaging is in vacuum-sealed moisture-barrier aluminum-laminated bags inside lined drums. Store in a cool, dry environment away from heat sources, direct sunlight, acidic vapors, and reducing atmospheres. Once opened, reseal the inner moisture-barrier bag promptly and store in a dry box or dry room. Prolonged exposure to ambient humidity increases surface LiOH and Li₂CO₃ content and can degrade slurry rheology and electrochemical performance.
Safety:
For research and industrial use only. Wear appropriate PPE (chemical-resistant gloves, safety glasses, lab coat, N95 or equivalent dust respirator) when handling M2-S powder, especially during weighing, transfer, and slurry preparation. Avoid generating dust; transfer powders in a fume hood, glovebox, or with local exhaust ventilation. Avoid contact with skin and eyes; in case of contact, flush with water and seek medical attention. M2-S contains nickel, cobalt, and manganese, which are regulated heavy metals — handle and dispose of in accordance with local environmental and occupational health regulations. High-nickel NCM materials have reduced thermal stability compared with medium-nickel NCM and may decompose with oxygen release under high-temperature or over-voltage abuse — avoid prolonged exposure to elevated temperatures and do not over-charge cells beyond the rated upper limit. Refer to the included Safety Data Sheet (SDS) for complete safety information.
Note: Specifications listed above are typical and for reference only. Actual electrochemical performance depends on the specific cell architecture, electrolyte formulation, binder/conductive-additive composition, coating thickness, calendering parameters, formation protocol, and testing conditions — consult published literature and our technical team for guidance on specific single-crystal Ni83 NCM electrode protocols. The BTR M2-S is a single-crystal high-nickel NCM cathode material suitable for laboratory and small-batch cell development targeting high energy density and extended cycle life.
