General description

Cobalt(II) hydroxide is a versatile compound with various applications in battery manufacturing, sensors, supercapacitor, and magnetic materials. It is also used as a key component in the production of rechargeable lithium-ion batteries. Additionally, it is also used in electrochemical reactions, including the oxidation of glucose and the oxygen evolution reaction (OER).

Application

Cobalt(II) hydroxide can be used in the research and development :
  • As an additive in Ni-based rechargeable alkaline batteries, including Ni-Cd and Ni-MH batteries, to improve their electrochemical performance.   
  • To synthesize reduced graphene oxide/cobalt hydroxide (rGO/Co(OH)2) composite material, which exhibits enhanced electrochemical performance for supercapacitor applications.     
  • As a electrode material for high-performance supercapacitors. It exhibits high specific capacitance and long cycling stability, making it a promising electrode material for supercapacitors.
