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.
A standard negative electrode manufacturing technology for automotive Ni–MH cells is the slurry coating process. The paste consists of an alloy powder capable of reversibly storing hydrogen, binder materials, and carbon powders as the main constituents.
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.
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.
In such electrode technology, the negative precharge is set to a higher level than that of the sintered technology to increase the electrode conductivity in the discharged state due to the larger distance between the steel strip and the active material.
Markin and Dell (1981) demonstrated the fabrication of metal hydride negative electrode by mixing small quantity of LaNi 5 with binder and pasted onto Ni grids. 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).
