Claim 19:
20. A system for producing a homogenized mixture of carbon, sulfur, and PTFE, comprising:
a first dosing screw having at least one heating element, which liquefies sulfur into liquid sulfur;
an injector receiving the liquid sulfur;
a second dosing screw providing carbon in a form of carbon particles;
a feed line receiving the liquid sulfur from the injector and the carbon from the second dosing screw;
a first mill connected to the feed line and grinding the liquid sulfur together with the carbon for a first time, so that the liquid sulfur is absorbed by pores of the carbon particles and forms a powdery composite with the carbon particles;
a third dosing screw providing PTFE, which is added with the powdery composite in a storage container to form a mixture; and
a second mill grinding for a second time the mixture to homogenize the mixture, wherein the first and second mills are impact mills arranged one behind the other in a transport direction of the mixture.
