Used as a catalyst in fuel cells and electrochemical devices due to its redox activity and stability. Employed in lithium-ion batteries as a cathode material component, enhancing charge-discharge efficiency. Applied in pigments for ceramics and glass, providing blue to green coloration. Utilized in electroplating processes to improve wear and corrosion resistance. Also used as a precursor in the production of magnetic materials. Investigated for use in supercapacitors and water splitting systems for hydrogen production.
