Used as a catalyst in chemical reactions, particularly in hydrogenation and electrochemical processes. Employed in the production of nickel-based batteries and electronic components due to its electroactive properties. Applied in coatings and surface treatments to enhance corrosion resistance. Also investigated for use in energy storage systems like supercapacitors and lithium-ion battery cathodes. Its layered structure makes it suitable for ion-exchange applications and as a precursor in synthesizing other nickel-containing materials.
