For the negative electrodes, water has started to be used as the solvent, which has the potential to save as much as 10.5% on the pack production cost. For the positive electrodes, on the other hand, the adoption of water as a solvent would require alternative binders, since PVDF is insoluble in water. Yet, a higher operating voltage window for

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.
Selection on the negative electrode is also an important issue in DIBs because it co-determines the performance of cells (i.e. rate capabilities, cyclic stability, specific capacity, safety and so forth) with positive electrode material and other components in cells.
In most methods for manufacturing battery electrodes, the dry mixing of materials is a distinct step that often needs help to achieve uniformity, particularly on a large scale. This lack of homogeneity can result in variable battery performance.
The dry-film-production approach streamlines the manufacturing of LIBs by eliminating the traditional solvent mixing, coating, drying, and solvent recovery steps. This reduction in process complexity also results in significant energy and equipment expense savings. As a result, this has greatly improved the efficiency of battery production.
In the case of both LIBs and NIBs, there is still room for enhancing the energy density and rate performance of these batteries. So, the research of new materials is crucial. In order to achieve this in LIBs, high theoretical specific capacity materials, such as Si or P can be suitable candidates for negative electrodes.
