Half-cell Spacer Material for Enhanced Flow Distribution

Abstract

Disclosed is method for enhancing electrolyte flowing mechanism within electrodes in flow battery cells by employing half-cell spacer screens that may be welded to at least one surface of each electrode sheet. Half-cell spacer screens may provide a constant gap thickness between electrode sheet and micro-porous separator membrane. Half-cell spacer screens may be made of a bromine inert thermoplastic such as polypropylene or polyethylene and may include at least one thin layer of strands. Additionally, the disclosed half-cell spacer screens may exhibit diamond pattern netting or any other suitable pattern. The inclusion of half-cell spacer screens may allow an improved distribution of electrolyte throughout the surface of electrode sheet, thereby improving performance flow batteries.
