A cathode unit for a solid-state battery and a method for producing the cathode unit. The cathode unit has a layer made of a composite material () which has an electrode material, a solid electrolyte material, an electrically conductive conducting additive and polyetrafluoroethylene as a binder. The composite material contains less than 1 wt. % polyetrafluoroethylene and the polyetrafluoroethylene is present, at least in part, as fibrillated polyetrafluoroethylene.

Cathode unit and method for producing a cathode unit

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.
