Patent ID: 10069161

Abstract:
A flow redox battery system including an electrochemical cell, an anolyte tank, a catholyte tank, a first anolyte carrier slurry, a second anolyte carrier slurry, a first catholyte carrier slurry, a second catholyte carrier slurry, and a power generation circuit. An ion-exchange membrane is electrochemically engaged with an anode and a cathode. The power generation circuit is electrically coupled to the anode and the cathode. The anolyte tank is fluidly coupled to the anode and the catholyte tank is fluidly coupled to the cathode. The first anolyte carrier slurry includes a density less than a density of the second anolyte carrier slurry and an electronegativity different than an electronegativity of the second anolyte carrier slurry. Further, the first catholyte carrier slurry includes a density less than a density of the second catholyte carrier slurry and an electronegativity different than an electronegativity of the second catholyte carrier slurry.
