A method for producing a conductive composite material for a battery such as a solid-state battery includes providing an ion-conducting electrolyte matrix that can be plasticized and that includes an ion-conducting first substance a base substance that can be plasticized and/or a polyelectrolyte; providing a second ion-conducting substance in the form of ion-conducting particles; introducing the ion-conducting particles into the electrolyte matrix to produce a mixture consisting of the ion-conducting particles and the electrolyte matrix; and homogenizing the mixture.

A method for the production of an electrode powder mixture for a battery cell includes filling an active material, a binder and a conductive additive into a filling section of a machine that has a driven screw which extends in the lengthwise direction and which serves for thoroughly blending and conveying a powder in the lengthwise direction. The screw blends the binder, the active material and the conductive additive in order to form a first powder, and the screw makes a second powder out of the first powder in that the binder is fibrillated. The screw produces the electrode powder mixture out of the second powder in that the fibrillated binder is comminuted, and the electrode powder mixture is removed from the machine at a removal opening, whereby the removal opening is at a distance from the filling section in the lengthwise direction.
