Abstract: A method for preparing a redox flow battery electrolyte is provided. In some embodiments, the method includes the processing of raw materials containing sources of chromium ions in a high oxidation state. In some embodiments, a solution of the raw materials in an acidic aqueous solution is subjected to a reducing process to reduce the chromium in a high oxide state to an aqueous electrolyte containing chromium (III) ions. In some embodiments, the reducing process is electrochemical process. In some embodiments, the reducing process is addition of an inorganic reductant. In some embodiments, the reducing process is addition of an organic reductant. In some embodiments, the inorganic reductant or the organic reductant includes iron powder.
Abstract: A quencher for a flow cell battery is described. The quencher utilizes a quench solution formed from FeCl2 in a dilute HCl solution in order to quench chlorine emissions from the flow cell battery. A quench sensor is further described. The quench sensor monitors the concentration level of FeCl2 in the quench solution and may also monitor the level of the quench solution in the quencher.

Abstract: A method for bonding a porous flexible membrane to a rigid material is disclosed. In some embodiments, the method includes applying, at a bonding site of the porous membrane, a pre-treatment solvent solution, drying the bonding site of the porous membrane, applying, at a bonding site of the rigid structure, a first solvent that is capable of dissolving a surface of the rigid material, applying, at the bonding site of the porous membrane, a second solvent that is capable of dissolving the polymeric residue material dissolved in the pre-treatment solvent solution, and pressing the porous membrane to the rigid material at their respective bonding sites. In some embodiments, the pre-treatment solvent solution may include a solvent carrying dissolved polymeric residue material configured to fill the pores of the porous membrane at the bonding site of the porous membrane.
