Abstract
An improved chemical composition and manufacturing process for a battery electrode are disclosed. This battery electrode may be later arranged in flowing electrolyte battery cells. Battery electrode material formulation may include a mixture of polypropylene, carbon black, graphite, bonding additives and other substances in different concentrations. The inclusion of graphite may reduce the amount of carbon black in the mixture, thereby reducing the swelling of the battery electrode in the presence of bromine. Moreover, material formulation may reduce warpage caused by the swelling of electrode material, and may additionally improve the performance and properties of flowing electrolyte batteries. An extrusion molding process may be employed in order to fabricate the disclosed battery electrode.
