摘要： A redox flow battery pipe which is disposed between a tank that stores an electrolyte and a battery element and through which the electrolyte flows includes a plurality of parallel portions arranged in parallel and a plurality of bent portions connecting the parallel portions adjacent to each other. The pipe includes a meandering portion in which the parallel portions and the bent portions are integrally molded so as to be alternately connected. A ratio of a center-to-center distance X to an outer diameter D satisfies 1.2 or more and 2.5 or less where D represents an outer diameter and X represents a distance between centers of the parallel portions adjacent to each other.

摘要： Disclosed herein are a system and method for producing a high-purity and high-activity vanadium electrolyte, comprising converting high-purity vanadium oxytrichloride into an ammonium salt in a fluidized bed (2) by gas phase ammoniation, then in another fluidized bed (3), reducing the ammonium salt into a low-valence vanadium oxide having an average vanadium valence of 3.5, adding clean water and sulfuric acid for dissolution, and further performing activation by ultrasound to obtain a 3.5-valence vanadium electrolyte which can be directly used in a new all-vanadium redox flow battery stack. The method of producing an ammonium salt containing vanadium in the fluidized bed (2) by gas phase ammoniation is of short process and high efficiency. Precise regulation of the valence state of the reduction product is implemented by arranging an internal member in the reduction fluidized bed (3), and ultrasonication is used to activate the vanadium ion, thereby greatly improving the activity of the electrolyte. The present method has the advantages of short process, high efficiency and good cleanliness, and stable product quality, etc. and is applicable to large-scale industrial production, with good economic and social benefits.

摘要： State of charge determination within electrochemical systems, such as flow batteries, can often be difficult to measure, particularly in an in situ manner. Methods for assaying the condition of an electrochemical system can include: interacting electromagnetic radiation with a first electrolyte solution at a location within the electrochemical system, the electromagnetic radiation being delivered through an optical material configured to exhibit attenuated total reflectance at an interface between the optical material and the first electrolyte solution; receiving at a detector electromagnetic radiation that has interacted with the first electrolyte solution via one or more attenuated total reflectances within the optical material; and measuring an absorbance of at least one of an oxidized form or a reduced form of a first coordination compound within the first electrolyte solution via the electromagnetic radiation that is received at the detector.

摘要： Solids can sometimes form in one or more electrolyte solutions during operation of flow batteries and related electrochemical systems. Over time, the solids can accumulate and compromise the integrity of flow pathways and other various flow battery components. Flow batteries configured for mitigating solids therein can include an autonomous solids separator, such as a lamella clarifier. Such flow batteries can include a first half-cell containing a first electrolyte solution, a second half-cell containing a second electrolyte solution, a first flow loop configured to circulate the first electrolyte solution through the first half-cell, a second flow loop configured to circulate the second electrolyte solution through the second half-cell, and at least one lamella clarifier in fluid communication with at least one of the first half-cell and the second half-cell. A hydrocyclone can be used as an alternative to a lamella clarifier in some instances.
