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. 本发明提供制造具有包含活性材料和可熔聚合物的功能性涂层的箔的无溶剂工艺、具有功能性涂层的箔，及其用作电极箔、固态电池中的电解质或用于电化学存储装置的分隔器的用途。所述工艺包括将干粉混合物散布到箔上，熔融干粉混合物，并压延覆盖有熔融粉末的箔。
