Abstract
A system for a flow cell for a hybrid flow battery, comprising: a redox plate comprising a plurality of electrolyte flow channels; conductive inserts attached to the redox plate between adjacent electrolyte flow channels; a redox electrode attached to a surface of the redox plate; a plating electrode, comprising: a plurality of folded fins with an oscillating cross-section, the plurality of folded fins comprising: a first planar surface; a second planar surface, parallel to the first planar surface; a plurality of ridges intersecting the first and second planar surfaces such that the plurality of ridges divide the first planar surface into a first plurality of strips, and divide the second planar surface into a second plurality of strips; and a membrane barrier. In this way, the capacity and performance of hybrid flow batteries may be maximized, through decreasing the reaction kinetics, mass transport and ohmic resistance losses at both electrodes.
