PROCESS FOR THE SOLVENT-FREE COATING OF FOILS FOR ELECTROCHEMICAL APPLICATIONS

The present invention provides a solvent-free process for producing foil with a functional coating containing an active material and a meltable polymer, the foil with a functional coating and its use as an electrode foil, electrolyte in solid-state batteries or separator for electrochemical storage. The process comprises scattering a dry powder mixture onto a foil, melting the dry powder mixture, and calendering the foil covered with the molten powder.
