    摘要: 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.

    摘要: A stationary probe having a probe holder and a probe with a probe tip. The stationary probe may be part of a stationary probe rotating disk electrode wherein the stationary probe has a passage therethrough for rotatably receiving a rotating disk electrode comprising a rotating shaft, rotatable about a longitudinal axis, and having an electrode portion extending therefrom configured to receive an electrode. The stationary probe rotating disk electrode may be part of an analytical system wherein the probe tip includes a capillary entrance spaced apart from the electrode and connected to an analyte flow path.
