Abstract
Electrode arrangement for electrochemical cells. A deformable sandwich structure (working electrode, insulator, secondary electrode, insulator) forms a primary electrode arrangement. A three-dimensional structure can be formed by rolling up the primary sandwich structure around and axis. The shapes and material structures of electrodes and insulators co-operate with each other to enable axial and/or radial flow of an electrolyte which is pumped through the electrode roll. With such electrode rolls a high ratio of electrode surface to cell volume can be attained. Furthermore, by mounting one or more of the electrode rolls on a hollow axle and pumping the electrolyte through orifices of the axle from its interior into the electrode rolls, the scale-up of current and voltage of a cell is considerably facilitated and advantageously achieved.
