A molding, preferably a film-like molding, is produced by a process which comprises the following stage: n I) Compounding and extruding the melt of a mixture I which comprises a mixture II which contains: n a) from 1 to 95% by weight of at least one pigment III which has a primary particle size of from 5 nm to 20 μm and is selected from the group consisting of an electrochemically inert solid IIIa, a compound IIIb capable of releasing lithium ions on charging and a compound IIIc capable of accepting lithium ions on charging and a mixture of the solid IIIa with the compound IIIb or the compound IIIc, n b) from 5 to 99% by weight of at least one copolymer IV of vinylidene fluoride (VdF) and hexafluoropropylene (HFP) containing from 8 to 25% by weight of HFP and n c) from 1 to 200% by weight, based on the total amount of the components a) and b), of a plasticizer V which is selected from the group consisting of dibutyl phthalate, dimethyl phthalate, diethyl phthalate, tris(butoxyethyl) phosphate, propylene carbonate, ethylene carbonate, trimethyl trimellitate and mixtures of two or more thereof, n the proportion of the mixture II in the mixture I being from 1 to 100% by weight. |
