General description

Cobalt(II) chloride hexahydrate, a hydrated form of cobalt chloride, is employed in electroplating and catalyst preparation. It serves as a precursor for synthesizing electrode materials for lithium-ion batteries and acts as a catalyst in a range of organic reactions, including acetylation, tosylation of alcohols, and condensation reactions.

Application

Cobalt(II) chloride hexahydrate can be used as:      
  • An additive to the electron transport layer (ETL) in perovskite solar cells to improve their performance, particularly by reducing energy losses and increasing the open-circuit voltage.      
  • A cobalt source for doping ZnO nanostructures. The incorporation of cobalt ions into the ZnO matrix is crucial for modifying its electronic and optical properties.      
  • A precursor to modify cobalt metal-organic framework (Co-MOF) derived carbon microspheres for application as anode materials in lithium-ion batteries.
