Abstract
A method for producing a solid electrolyte membrane () or an anode unit for a solid-state battery, in which method a powder mixture consisting of a solid electrolyte material and polytetrafluoroethylene is produced for the solid electrolyte membrane () and a powder mixture consisting of an electrode material, a solid electrolyte material, an electrically conductive conduction additive and polytetrafluoroethylene is produced for the anode unit, at least partially fibrillated polytetrafluoroethylene is formed by applying shear forces to the powder mixture, and the powder mixture is shaped into a flexible composite layer. The powder mixture has at most 1 wt. % polytetrafluoroethylene.
