Schematics of batteries made of a metal negative electrode (for example lithium), a positive electrode containing cathode active material (CAM) particles and an electrolyte, forming either a a) LEB or GEB, b) DPEB or PPEB, c) SEB, d) particle-in-matrix HEB, or e) multilayer HEB.
In a real full battery, electrode materials with higher capacities and a larger potential difference between the anode and cathode materials are needed.
Several new electrode materials have been invented over the past 20 years, but there is, as yet, no ideal system that allows battery manufacturers to achieve all of the requirements for vehicular applications.
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).
This mini-review discusses the recent trends in electrode materials for Li-ion batteries. Elemental doping and coatings have modified many of the commonly used electrode materials, which are used either as anode or cathode materials. This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity.
