    Abstract: An ionically conductive asymmetric composite membrane for use in redox flow battery, fuel cell, electrolysis applications and the like is described. It comprises a microporous substrate membrane and an asymmetric hydrophilic ionomeric polymer coating layer on the surface of the microporous substrate layer. The coating layer is made of a hydrophilic ionomeric polymer. The asymmetric hydrophilic ionomeric polymer coating layer comprises a porous layer having a first surface and a second surface, the first surface of the porous layer on the surface of the microporous substrate layer and a nonporous layer on the second surface of the porous support layer. The microporous substrate membrane is made from a different polymer from the hydrophilic ionomeric polymer.

    Abstract: Low cost membrane electrode assemblies (MEA) with improved coulombic efficiency (CE), reduced maintenance cost, and improved deliverable capacity have been developed for redox flow batteries and other electrochemical reaction applications. The MEA comprises: a microporous substrate membrane, first and second hydrophilic ionomeric polymer coating layers on surfaces of the microporous substrate membrane, and an electrode adhered to a second surface of the second hydrophilic ionomeric polymer coating layer. Methods of preparing the MEA and a redox flow battery system incorporating the MEA are also described.

    Abstract: Stable and high performance positive and negative electrolytes compositions to be used in redox flow battery systems are described. The redox flow battery system, comprises: at least one rechargeable cell comprising a positive electrolyte, a negative electrolyte, and an ionically conductive membrane positioned between the positive electrolyte and the negative electrolyte, the positive electrolyte in contact with a positive electrode, and the negative electrolyte in contact with a negative electrode. The positive electrolyte consists essentially of water, a first amino acid, an inorganic acid, an iron precursor, a supporting electrolyte, and optionally a boric acid. The negative electrolyte consists essentially of water, the iron precursor, the supporting electrolyte, and a negative electrolyte additive. The iron precursor is FeCl2, FeCl3, FeSO4, Fe2(SO4)3, FeO, Fe, Fe2O3, or combinations thereof. The supporting electrolyte is LiCl, NaCl, Na2SO4, KCl, NH4Cl, or combinations thereof. The negative electrolyte additive is boric acid or a combination of the boric acid and a second amino acid.

    Abstract: A poorly crystalline mixed metal manganese oxide material. The mixed metal manganese oxide material may be used for making a cathode for a rechargeable battery. Generally, the mixed metal manganese oxide includes: manganese oxide; copper, silver, gold, or a combination thereof; a first additional cation selected from the group consisting of: bismuth, lead, and mixtures thereof; and a second additional cation selected from the group consisting of: lithium, sodium, potassium, cesium, rubidium, beryllium, magnesium, calcium, strontium, barium, NR4+, or a combination thereof, with R being, hydrogen, an alkyl group, an aryl group, or combinations thereof. The amorphous composition has an essentially amorphous x-ray powder diffraction pattern.
