    Abstract: A homogenously mixed metal manganese oxide. The mixed metal manganese oxide includes a homogenous mixture of manganese and at least two more metals. The additional metals may be cesium, nickel, copper, bismuth, cobalt, magnesium, iron, aluminum, scandium, vanadium, chromium, silver, gold, titanium, or, lead. A method of making the metal manganese oxide material includes mixing salts of manganese and the additional metals. The mixture may be activated and digested at an elevated temperature. Also, a battery having a cathode made from the homogenously mixed metal manganese oxide.

    Abstract: A hydroprocessing catalyst or catalyst precursor has been developed. The catalyst is a crystalline transition metal tungstate material or metal sulfides derived therefrom. The hydroprocessing using the crystalline ammonia transition metal tungstate material may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.

    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: Devices and methods for managing the state of health of an electrolyte in redox flow batteries (RFB) efficiently are described. A diffusion cell is added to the RFB which controls one or more properties of the electrolytes using the diffusion of protons through a proton exchange membrane. The diffusion cell can resemble an electrochemical cell in that there are two fluid chambers divided by a proton conducting membrane. Anolyte flows through one side of the device where it contacts the proton conducting membrane, and catholyte flows through the second side of the device where it contacts the other face of the proton conducting membrane. The concentration gradient of protons from high concentration in the catholyte to low concentration in the anolyte is the driving force for proton diffusion, rather than electromotive force, which greatly simplifies the design and operation.
