Methods for preparing titanium catecholate complexes can include combining one or more catecholate ligands and titanium oxychloride in an aqueous solution, and reacting the one or more catecholate ligands with the titanium oxychloride in the aqueous solution to form the titanium catecholate complex. Titanium tetrachloride can be used as a precursor for forming the titanium oxychloride in situ. In some instances, the titanium catecholate complex can be isolated in a solid form, which can be substantially free of alkali metal ions.

  • Patent number: 9966625
    Abstract: The present invention provides a non-aqueous redox flow battery comprising a negative electrode immersed in a non-aqueous liquid negative electrolyte, a positive electrode immersed in a non-aqueous liquid positive electrolyte, and a cation-permeable separator (e.g., a porous membrane, film, sheet, or panel) between the negative electrolyte from the positive electrolyte. During charging and discharging, the electrolytes are circulated over their respective electrodes. The electrolytes each comprise an electrolyte salt (e.g., a lithium or sodium salt), a transition-metal free redox reactant, and optionally an electrochemically stable organic solvent. Each redox reactant is selected from an organic compound comprising a conjugated unsaturated moiety, a boron cluster compound, and a combination thereof. The organic redox reactant of the positive electrolyte comprises a tetrafluorohydroquinone ether compound or a tetrafluorocatechol ether compound.

  • Patent number: 9689624
    Abstract: A battery module with one or more battery cells and a heat exchange member placed in thermal communication with the battery cell, and a method of making a heat pipe system from the heat exchange member. The heat exchange member includes a container with a heat transfer fluid disposed therein. In one form, the heat transfer fluid is capable of going through a phase change as a way to absorb at least a portion of heat present in or generated by battery cell. A pressure control device cooperates with the container and heat transfer fluid such that upon attainment of a predetermined thermal event within the battery cell, the pressure control device permits liberation of at least a portion of the heat transfer fluid to an ambient environment, thereby relieving pressure on the container and removing some of the excess heat caused by the thermal event.
