A method to produce a composite semi-finished product, having a continuous phase including at least one thermoplastic plastic and a dispersed phase made from at least one electrically conductive filler. The at least one thermoplastic plastic in form of fine particles is mixed with the at least one filler in the form of fine particles. In each case, at least 90% by weight of the particles of the at least one thermoplastic plastic and of the at least one filler are smaller than 1 mm. The mixture of the at least one thermoplastic plastic and the at least one filler is heated to a temperature greater than the melting temperature of the at least one thermoplastic plastic. The heated material is cooled to a temperature below the solidification temperature of the at least one thermoplastic plastic.

Method to produce a composite semi-finished product

A redox flow battery is illustrated and described, having at least one cell frame enclosing a cell interior and having at least one supply line provided outside the cell frame for supplying electrolyte to the cell interior and/or at least one disposal line provided outside the cell frames for removing electrolyte from the cell interior. In order to provide greater degrees of freedom in the design of the cell so as to make available redox flow batteries with improved properties, it is envisaged that the supply line for supplying electrolyte to the cell interior and/or the disposal line for removing electrolyte from the cell interior is in fluid contact with the cell interior via a plurality of separate flow channels in the cell frame.
