Sigma-Aldrich Cobalt(Ii) Hydroxide Battery Grade >=&

Cobalt(II) hydroxide, also known as cobaltous hydroxide, is an inorganic compound with the chemical formula Co(OH)₂. It typically appears as a pink to red powder or crystalline solid. We offer Cobalt(II) hydroxide, battery grade with high purity of ≥99.9%, and controlled low impurities such as Chloride ≤ 50 ppm, NO3 <50 ppm, Acid insoluble<50 ppm. With very low water content of <2%, the product is ideal for research areas in rechargeable batteries, supercapacitors.

Cobalt(II) hydroxide, battery grade, with a purity of ≥99.9% trace metals basis, is a high-purity material used in several advanced applications, particularly in the energy storage and battery industries. It can be used for research areas to design supercapacitors and alkaline zinc ion batteries; as it is a promising electrode material due its high capacitance and long cyclability. [[1],[2]] It is also used as a precursor for designing cathode materials in Lithium–sulfur (Li-S) batteries. In a study it has been found that double-shelled nanocages with two shells of cobalt hydroxide and layered double hydroxides (CH@LDH) designed for a Li-S battery, significantly improved the electrochemical performance.[3]] Due to its redox properties, cobalt(II) hydroxide is employed as a precursor for the preparation of cobalt-based catalysts. These catalysts are used in various industrial processes, including the synthesis of fine chemicals, petrochemical refining, and environmental remediation. Cobalt(II) hydroxide is used in the production of soft magnetic materials, which are employed in electronic devices, sensors, and other applications requiring efficient magnetic properties. [4]

Cobalt(II) hydroxide, battery grade, is engineered with tightly controlled low impurities and minimal water content, making it ideal for battery research applications. With a purity of ≥99.9% and minimal trace metal impurities, the product is ideal for use in sensitive processes where contamination must be strictly controlled.
