Currently, nearly 40% of cobalt consumption is used for rechargeable battery materials, such as lithium cobaltate for lithium-ion batteries, cobaltous oxide for nickel-metal hydride batteries, etc. The primary use of cobalt is in lithium batteries. One of the cores of lithium-ion batteries is its positive electrode material, in which lithium cobalt oxide (LiCoO2) is used. Lithium cobalt oxide is a solid electrolyte with high energy density and environmental safety. The advantages of lithium batteries are wide voltage range, high energy density, and environmental protection (compared with Ni-Cd and Ni-Mn).
Cobalt is also widely used in the medical field. The radioactive isotope of cobalt can treat skin diseases and malignant tumours. Adding an appropriate amount of cobalt to penicillin can improve its curative effect. Cobalt content is as high as 4.5% in vitamin B12 (alias cobalamin), which has unique effects on hematopoiesis. In addition, cobalt is also used in artificial joint materials and dental fillings.
