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).
One of the requirements for this application is that the graphite surface must be compatible with lithium-ion battery chemistry (salts, solvents and binders). As previously mentioned, the most essential material in the anode is graphite.
To stabilize the now negatively charged cathode, Li+ ions move from in between the graphite sheets in the anode, to the cathode. The anode (or negative electrode) in a lithium-ion battery is typically made up of graphite, binder and conductive additives coated on copper foil.
