AB - IntroductionThe process step of drying represents one of the most energy‐intensive steps in the production of lithium‐ion batteries (LIBs).[1,2] According to Liu et al., the energy consumption from coating and drying, including solvent recovery, amounts to 46.84% of the total lithium‐ion battery production.[3] The starting point for drying battery electrodes on an industrial scale is a wet film of particulate solvent dispersions, which are applied to a current collector foil by slot‐die coating. Conventional convective drying removes the solvent from the wet film and solidifies the layer as the drying time progresses (Figure 1). According to the state‐of‐the‐art, electrodes are produced at a web speed of 25–80 m min−1.[2,4–8]1FigureConvective drying: a) Nozzles blow heated air on the coating to be dried; b) introducing heat into the coating from above and transporting away the solvent.The deviations in the coating/drying speeds are related to the constant improvement of the system technologies and the different coating thicknesses and types. For example, coatings can be applied intermittently or continuously.[9–11] Furthermore, double‐sided coatings can be applied simultaneously or sequentially, meaning that the first side is dried first and then the second side.[4,6,7,12] In addition to the actual application methods, parameters such as mass loading and solids content
