cobalt aluminum is a metal alloy used in aerospace applications and medical equipment. It is highly resistant to cavitation, erosion, corrosion and galling. It has high strength at elevated temperatures, is light in weight and easy to machine. Cobalt also confers good wear and abrasion resistance in combination with other metallic elements. Alloying with other metals allows for the creation of materials which are useful for specific purposes, such as adding chromium to cobalt to create the blue pigment known as cobalt blue, which is used in paint and dyes.
Lithium nickel cobalt aluminum oxides (abbreviated as NCA) are important lithium ion battery materials. These are used as the active material in the positive electrode of lithium ion batteries. NCA is a complex mixture of cations, with the lithium, nickel, cobalt and aluminium ions in a matrix of alumina.
In this paper, the influence of the activation procedure on the catalytic performance of a cobalt-based nickel-cobalt-aluminum (Co-Ni-Al) catalyst was investigated. This was done by performing rotating ring disk electrode voltammetry experiments with different potentials and concentrations of cobalt(II) solution. The results showed that the deposit morphology was strongly dependent on the cobalt concentration/deposition potential, with deposits obtained at higher potentials consisting of larger nodules of pure
There is a strong push globally from major car manufacturers and battery companies to source all cobalt in a responsible manner, with evidence of traceability and sustainable production. There are a number of initiatives in place, such as the Responsible Cobalt Initiative and the Cobalt for Development study.
