Further solvent addition is an important parameter that impacts slurry processing and utilisation, such as mixing, coating, and drying. The amount of solvent that can be used mainly depends on the solvent-binder combination and the AM used . If the value of the corresponding solid content does not fall within this range, feedback is given to the user during the characterisation of the cell. If the solid content is too low, then the slurry does not have sufficient particle network structures capable of withstanding the weight of the coated slurry, leading to an unstable slurry that flows too much upon coating . If the solid content is too high, then the slurry takes more time to homogenise during mixing, which can lead to agglomeration-related defects during coating. It can also lead to a highly viscous slurry, which will need more advanced coating techniques than the traditional wet processing, which are still in development .
