The negative electrode material is the main body of lithium ion battery to store lithium, so that lithium ions are inserted and extracted during the charging and discharging process.
The manufacturing of negative electrodes for lithium-ion cells is similar to what has been described for the positive electrode. Anode powder and binder materials are mixed with an organic liquid to form a slurry, which is used to coat a thin metal foil. For the negative polarity, a thin copper foil serves as substrate and collector material.
For the negative electrode, usually a carbonaceous material capable of reversibly intercalating lithium ions is used. Depending on the technical and process demands, several different carbon materials and configurations (e.g., graphite, hard carbon) may be used.
As the negative electrode material of SIBs, the material has a long period of stability and a specific capacity of 673 mAh g −1 when the current density is 100 mAh g −1.
The active materials incorporated in the making of the electrode include AB 2 Laves type alloy (Moriwaki et al., 1989) and AB 5 hexagonal close-packed alloy (Iwakura et al., 1988). Farschad Torabi, Pouria Ahmadi, in Simulation of Battery Systems, 2020 In practice, most of negative electrodes are made of graphite or other carbon-based materials.
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).
