Lithium Hydroxide Monohydrate Battery Grade
CAS Number: 1310-66-3
Battery-grade lithium hydroxide monohydrate (LiOH·H2O, purity ≥56.5% LiOH) is the preferred lithium source for high-nickel NMC and NCA cathode synthesis, offering superior performance versus lithium carbonate at high Ni content. Strict control of Na, Fe, Ca, and Mg impurities ensures long-term cycle stability in EV battery packs.

Applications
- High-nickel NMC811/NMC90 cathode synthesis
- NCA cathode material production
- Single-crystal cathode material fabrication
- Lithium-sulfur battery electrolyte additive
- Solid-state battery solid electrolyte preparation
Key Features
- Higher reactivity than Li2CO3 ensures complete lithiation in high-Ni cathode calcination
- Low CO2 absorption grade packaging prevents carbonate conversion during storage
- Tight particle size distribution (D50 5–15 μm) improves mixing homogeneity
- Automotive-grade traceability with batch-level ICP-MS certificates
