Coperion offers solutions for the dry coating process for battery electrode manufacturing

Continuous manufacturing of dry coated electrodes for greater profitability

Environmentally friendly, energy-efficient and space-saving: The dry coating process eliminates the need for solvents and water, as well as the energy-intensive drying step.

After mixing, the powdery coating material is directly fed into a calender to create a thin sheet which is later applied to the electrode film. This approach not only enhances environmental performance and energy efficiency but also reduces costs and space requirements.

Your advantages at a glance

  • Cost-effective process by eliminating the drying step and reducing footprint requirements
  • Environmentally friendly production with no chemical solvents
  • Improved CAPEX and OPEX, thanks to simplified process stages

Extrusion

For the dry coating process, the continuous process using twin screw extruder is particularly fitting because it allows for simultaneous fibrillation of special binders and homogenization of raw materials. The shorter residence time in the extruder as well as the flexibility in applying thermal energy to the product or removing it from the product by controlling the temperature of individual barrel elements are but a few more advantages of this technology.

Material Handling

The binders used in the dry process require special temperature control throughout every stage, from conveying and feeding to mixing and handling the coating mass. It is essential to maintain specific temperature windows during these processes. To address this need, Coperion provides specially designed equipment that ensures both the handling and feeding of the binder into the mixer occur at defined temperatures.

Feeding

The new Loss-in-Weight Roller Feeder is a precise gravimetric device designed for continuous feeding of dry electrode coating powder blends directly into the calender gap. This system enhances process stability and repeatability, making it ideal for laboratory and pilot-scale production of high-quality electrode materials.
