Energy Consumption of the Coating and Drying Process

During the production process of battery electrodes, a thin layer of active material is applied onto a current collector substrate. This is done by using a slurry or paste which contains the active material. After coating, the electrode is then dried to remove any solvents or other volatile components from the slurry. This results in a solid and uniform layer of active material on the current collector. Temperatures of up to 200°C are required in the convection dryer. Once this process is complete, solvent recovery is carried out to remove the NMP from the hot air.
