The drying process of lithium-ion battery electrodes is one of the key processes for manufacturing electrodes with high surface homogeneity and is one of the most energy-consuming stages. The choice of the drying parameters has a significant impact on the electrode properties and the production efficiency.
In the study of drying techniques for lithium batteries, the key point is the relationship between the amount of electrode dewatering and various dominant factors during drying.
In recent years, initial investigations of electrode drying using lasers have been carried out and government-funded research projects like ExLaLib, [ 42, 43 ] LaserScale, [ 44 ] and Ideel [ 45, 46 ] look into the laser drying technology for lithium-ion battery electrodes.
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 ).

When fabricating battery electrodes, their properties are strongly determined by the adjusted drying parameters. This does not only affect their microstructure in terms of adhesion, but also influences cell performance. The reason is found to be the binder transported to the surface during drying.
