For high capacity Ion-Litium batteries, it is necessary to reduce the proportion of conductive additives and increase the ratio of active material. However, it is also important to have sufficient electron conductivity to reduce the internal resistance of the battery, and a moderate amount of conductive additives are required.
The sustainability of the process depends heavily upon the solvent used to disperse the slurry. [7, 8] Water-based slurries are preferred due to the toxicity of alternatives, and the lower cost.
