Nickel Sulfate (NiSO₄)

Description

1. Product Overview

Nickel Sulfate (NiSO₄) is a high-purity inorganic crystalline salt essential as a precursor for lithium-ion battery cathodes (NMC, NCA) and high-performance electroplating. Its primary value proposition is delivering consistent nickel ion availability to maximize cathode energy density and coating uniformity. With the EV battery sector expanding at over 25% CAGR, securing reliable NiSO₄ supply is a strategic imperative for cathode active material (CAM) manufacturers and plating operators globally.

2. Key Specifications & Technical Characteristics

• Chemical composition: NiSO₄·6H₂O (hexahydrate), Ni content ≥ 22.2% ± 0.3%

• Purity grade: Battery-grade (≥ 99.9%) / Electroplating-grade (≥ 99.5%)

• Physical characteristics: Emerald green crystalline powder; bulk density 0.9–1.1 g/cm³; particle size 80% through 80 mesh; free-flowing, low dust

• Impurity limits (max): Cu ≤ 2 ppm, Co ≤ 5 ppm, Fe ≤ 2 ppm, Zn ≤ 2 ppm, Pb ≤ 2 ppm, Ca+Mg ≤ 50 ppm, water insolubles ≤ 0.01%

• Packaging options: 25 kg PE-lined woven bags, 1 MT jumbo bags, or 20 MT container liner bags

• Shelf life: 24 months in original sealed packaging stored below 35°C, < 70% RH

3. Core Industrial Applications

• Lithium-ion battery cathode production: Used directly in co-precipitation of NMC (nickel-manganese-cobalt) and NCA precursors. Battery-grade NiSO₄ ensures higher first-cycle efficiency and lower impedance than standard grades, reducing cell rejection rates by up to 8%.

• Electroplating (decorative & functional): Provides uniform nickel deposition on automotive trim, connectors, and circuit boards. Its low chloride and boric acid tolerance allows faster plating baths (10–15% higher current density) compared to competing sulfate sources.

• Catalyst & textile mordant: Acts as a stable nickel source for hydrogenation catalysts; superior solubility reduces catalyst prep time.

4. Competitive Advantages

• Quality consistency: Every batch certified with ICP-OES traceability; lot-to-lot purity variance < 0.05%, eliminating process recalibration for CAM lines.

• Supply reliability: 5,000 MT monthly capacity from vertically integrated refining, backed by LME-linked long-term contracts and safety stock at three regional warehouses (Asia, EU, NA).

• Logistics capability: Door-to-door shipment with blockchain-based chain of custody; average lead time 14 days from PO to port of loading.

• Cost & sustainability: Competitive index-linked pricing within ±3% of Platts benchmark; zero liquid discharge (ZLD) production process reduces water footprint by 60% vs conventional sulfate.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 metric tons (MT) – one full container load for contract pricing

• Bulk loading capacity: 20–22 MT per standard 20-ft dry container (loaded in jumbo bags or container liner)

• Incoterms offered: FOB, CIF, CFR, EXW (depending on origin)
