Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
For lithium-ion batteries, the most in-depth studied material for the cathode is cobalt oxides and lithiated nickel. The high stability of structure characterizes both of them. They are expensive and difficult to make as the resources are limited. In the development of these layered compounds’ solid solutions, there is a resolution.
Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
