Abstract

A method for producing a homogenized mixture of carbon, sulfur, and PTFE, wherein the sulfur is liquefied, and the liquid sulfur is then ground for the first time together with the carbon, so that the liquid sulfur is absorbed by the pores of the carbon particles and forms a preferably powdery composite with the carbon particles, whereupon PTFE is added and the mixture of the composite and the PTFE is then ground a second time and is thus homogenized.
