摘要:
Method for producing a composite semifinished product (1), with a continuous phase comprising at least one thermoplastic material (2) and a disperse phase consisting of at least one electrically conductive filler (3), wherein the at least one thermoplastic material is mixed in the form of fine particles with the at least one filler in the form of fine particles, wherein in each case at least 90% by weight of the particles of the at least one thermoplastic material and of the at least one filler are smaller than 1 mm, in which method the mixture (4) of the at least one thermoplastic material and the at least one filler is heated up to a temperature which is greater than the melting temperature of the at least one thermoplastic material, and in which method the heated material is cooled to a temperature below the solidification temperature of the at least one thermoplastic material.
摘要:
The invention illustrates and describes a cell (1) of a redox flow battery, having at least one cell frame element (2, 3, 4), a diaphragm (15) and two electrodes (5), wherein the at least one cell frame element (2, 3, 4), the diaphragm (15) and the two electrodes (5) surround two cell interior spaces (10) which are separate from one another, wherein at least four separate channels (6, 7, 8, 9) are provided in the at least one cell frame element (2, 3, 4) such that different electrolyte solutions can flow through the two cell interior spaces (10), and wherein the cell (1), with the exception of the at least four separate channels (6, 7, 8, 9), is of liquid-tight design. In order to be able to provide redox flow batteries with a relatively high power density, it is proposed that at least the at least one cell frame element (2, 3, 4) is welded to the diaphragm (15), the two electrodes (5) and/or to at least one further cell frame element (2, 3, 4).
摘要:
A redox flow battery (1, 1') is presented and described, having at least one cell frame (4) surrounding a cell interior space (7) and having at least one supply line (2, 2') provided outside the cell frame (4) for supplying electrolyte to the cell interior space (7) and/or at least one disposal line (3, 3') provided outside the cell frame (4) for removing electrolyte from the cell interior space (4). In order to make greater degrees of freedom available in designing the cell so as to provide redox flow batteries with improved properties to the maximum extent possible, it is intended that the supply line (2, 2') for supplying electrolyte to the cell interior space (7) and/or the disposal line (3, 3') for removing electrolyte from the cell interior space (7) is in fluidic contact with the cell interior space (7) via a plurality of separate flow channels (8, 14) in the cell frame (4).
