Cobalt hydroxide is a chemical compound containing 30-40% of cobalt. Cobalt is a mineral that has a high melting point (1493 degrees Celsius) that helps it to retain its strength to a high temperature and is also known to be ferromagnetic. Cobalt is typically mined as a by-product of copper or nickel. ~2/3 of global cobalt reserves and mining operations located in the Democratic Republic of Congo.
What is it used for
Cobalt-based blue pigments have been used since ancient times for jewellery and paints, and to impart a distinctive blue tint to glass. Today, the unique properties of cobalt make the metal perfect for two specialized high-tech purposes: superalloys and Li-on battery cathodes. Other cobalt uses also include magnets, catalysts, and prosthetics.
Cobalt hydroxide is almost exclusively used for production lithium-ion batteries that are used in electronics and electric vehicles. That makes it a critical element to facilitate energy transition and electrification of transport.
