Battery-Grade Nickel Sulfate for Cathode Production
Nickel sulfate hexahydrate (NiSO₄·6H₂O) is the main nickel source for lithium-ion battery cathodes, especially high-nickel NMC (such as NMC 811) and NCA chemistries used in electric vehicles. As EV makers move to higher-nickel cathodes for greater energy density, battery-grade nickel sulfate has become one of the most important battery raw materials.
Cavin Resources supplies battery-grade nickel sulfate to cathode precursor producers, battery material makers, platers and chemical traders.
Applications of nickel sulfate
- Battery cathode precursors – NMC and NCA pCAM production for EV and energy storage batteries.
- Electroplating – bright and decorative nickel plating, and electroless nickel.
- Catalysts – feedstock for nickel catalysts.
- Chemical production – intermediate for other nickel salts.
Typical specifications
- Chemical formula: NiSO₄·6H₂O
- Grade: battery grade, ultra-low impurity levels
- Nickel content: typically about 22% min
- Cobalt content: low, controlled to specification
- Appearance: green crystals
- Critical impurities (Fe, Cu, Zn, Pb, Ca, Mg, Na): controlled to battery-grade limits; confirm on the lot COA
Send us your cathode specification and we will confirm a matching lot and provide the COA.
Handling and safety
Nickel sulfate is classified as hazardous. It can cause skin and respiratory sensitisation and is a suspected carcinogen. Use gloves, eye protection and dust control, store sealed in a dry area, and follow the SDS supplied with each shipment.
The reference price shown is based on recent published battery-metal market index data and moves with EV/battery demand and nickel feedstock costs. Request a live quote before committing to volume.
Frequently asked questions
Can battery-grade nickel sulfate be used for plating?
Yes. Its high purity makes it suitable for plating, although plating-grade material is often more economical.
How is the price set?
Nickel sulfate follows nickel metal prices plus a premium for purity and form, so quotes are valid for a short period.
