Nickel Sulfate Hexahydrate Battery Grade (NiSO4·6H2O)
CAS Number: 10101-97-0
Battery-grade nickel sulfate hexahydrate (NiSO4·6H2O) is the primary nickel source for NMC and NCA cathode precursor (pNi-Co-Mn(OH)2) co-precipitation. Ultra-low impurity specifications (particularly Fe, Cr, Zn, and Na) are essential to ensure high-performance cathode active materials without electrochemical side effects.
Technical Specifications
| Cr (ppm) | ≤1 |
| Fe (ppm) | ≤2 |
| Na (ppm) | ≤20 |
| Zn (ppm) | ≤2 |
| appearance | Green crystalline powder or granules |
| purity (%) | ≥22.0 (as Ni) |
| moisture (%) | ≤0.3 |
Applications
- NMC (811/622/532/111) cathode precursor co-precipitation
- NCA cathode precursor synthesis
- High-nickel Ni-rich precursor for EV cathode
- Electroplating and surface finishing
- Catalyst and chemical synthesis intermediate
Key Features
- Ni content ≥22% (as element) meeting battery-grade co-precipitation feed requirements
- Fe ≤2 ppm and Cr ≤1 ppm prevent catalytic decomposition in precursor and cathode
- Consistent crystalline form ensures stable dissolution rate during continuous co-precipitation
- Full ICP-MS elemental analysis certificate with each batch delivery
