Battery Industry

Battery-grade Cobalt Sulfate is a raw material for the production of lithium cobalt oxide.Lithium cobalt oxide produced from Cobalt Sulfate can guarantee the energy density, cycle stability, and rate performance of lithium-ion batteries.
Battery-grade Cobalt Sulfate offers the advantage of recyclability in the field of battery recycling.

Agriculture and Animal Nutrition

Cobalt sulfate can increase the cobalt content in soil and crops through soil application, foliar spraying, and seed treatment, and is particularly effective in improving the nitrogen fixation capacity and yield of leguminous crops.
Feed-grade Cobalt Sulfate is a cobalt source supplement for animals (especially ruminants), and is used as an additive in trace element premixes to ensure sufficient levels of vitamin B12 in the animal’s body.

Industrial Sector

Industrial-grade Cobalt Sulfate can be used as a coloring agent, providing a stable and unique cobalt blue color to products such as ceramic glazes, glass, and enamel.
Industrial-grade Cobalt Sulfate can be used as a catalyst in fields such as petrochemicals, environmental protection and energy, and polymer polymerization.It is also as an accelerator for oxidative drying in paints and inks.
Electroplating-grade cobalt sulfate,as an additive in electroplating solutions, it is used to improve the surface of materials such as stainless steel, iron, and nickel alloys.To achieve the purpose of enhancing surface corrosion resistance, increasing material hardness, or improving appearance.
