Metal negative electrodes that alloy with lithium have high theoretical charge storage capacity and are ideal candidates for developing high-energy rechargeable batteries. However, such electrode materials show limited reversibility in Li-ion batteries with standard non-aqueous liquid electrolyte solutions.
Critical to battery function are electron and ion transport as they determine the energy output of the battery under application conditions and what portion of the total energy contained in the battery can be utilized.
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).
The anode and cathode electrodes play a crucial role in temporarily binding and releasing lithium ions, and their chemical characteristics and compositions significantly impact the properties of a lithium-ion cell, including energy density and capacity, among others.
In fact, the free energy of lithium metal is so high that all known electrodes have a positive voltage with respect to it. Although both electrodes in a Li-ion battery may operate ascathodes or anodes (during discharge or charge), positive electrodes are often called cathodes in the battery literature, with negative electrodes called anodes.
