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.
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.
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.
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).
