Used as a precursor in the production of cobalt-containing materials such as catalysts, batteries, and pigments. Commonly employed in the synthesis of cobalt oxides for lithium-ion battery cathodes due to its ability to intercalate lithium ions. Also utilized in electrochemical applications, including supercapacitors and sensors, where it contributes to charge storage and electron transfer. In industrial processes, it acts as an intermediate in the preparation of other cobalt salts and coordination compounds. Its layered structure supports use in ion-exchange systems and environmental remediation for capturing anionic pollutants. Additionally, it finds application in coatings and ceramics for imparting color stability and thermal resistance.
