7 Claims

1. A method for applying polymer patches from polymer electrode material on a carrier substrate, comprising:

a) plasticizing the polymer electrode material to form a melt,

b) feeding the plasticized polymer electrode material via at least one die to a heated, structured roller or to a heated, structured conveyor belt, wherein the roller and/or the conveyor belt have recesses having dimensions that are the same as dimensions of the patches to be applied, such that shapes of the recesses are negative forms of shapes of the patches, the feeding of the plasticized polymer electrode material including applying a contact pressure to the melt to fill the recesses, and

c) applying the plasticized polymer electrode material on a carrier substrate by bringing the roller and/or the conveyor belt in contact with a carrier substrate.
