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 copper collector of graphitic negative electrodes can dissolve during overdischarge and form microshorts on recharge. Preventing this is one of the functions of the battery management system (see 2.1.3). The electrode foils represent inert materials that reduce the energy density of the cell. Thus, they are made as thin as possible.
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
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).
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.
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.
