In accordance with embodiments of the present disclosure, a redox flow battery (RFB) may include a shell, an electrolyte storage tank assembly disposed in the shell, wherein at least a portion of the electrolyte storage tank assembly is supported by the shell, an electrochemical cell, and an electrolyte circulation system configured for fluid communication between the electrolyte storage tank assembly and the electrochemical cell. In some embodiments, at least a portion of the electrolyte storage tank assembly defines a tank assembly heat transfer system between an outer surface of the electrolyte storage tank assembly and an inner surface of the shell. In other embodiments, a pump assembly in the electrolyte circulation system is moveable between a first position and a second position. In other embodiments, a gas management system includes a first gas exchange device in fluid communication with the catholyte headspace and the anolyte.

Flow battery system

A method of operating a redox flow battery includes providing a redox flow battery including an anolyte storage tank configured for containing a quantity of anolyte and an anolyte headspace, a catholyte storage tank configured for containing a quantity of a catholyte and a catholyte headspace, and a gas management system comprising at least one open conduit interconnecting the anolyte headspace and the catholyte headspace for free gas exchange between the anolyte and catholyte headspaces, and a passive gas exchange device in gaseous fluid communication with the anolyte headspace, the passive gas exchange device configured to release gas from the anolyte headspace to an exterior battery environment when an interior battery pressure exceeds an exterior battery pressure by a predetermined amount, and operating the battery.

Gas management systems and methods in a redox flow battery

Redox flow battery systems having a supporting solution that contains Clions can exhibit improved performance and characteristics. Furthermore, a supporting solution having mixed SOand Clions can provide increased energy density and improved stability and solubility of one or more of the ionic species in the catholyte and/or anolyte. According to one example, a vanadium-based redox flow battery system is characterized by an anolyte having Vand Vin a supporting solution and a catholyte having Vand Vin a supporting solution. The supporting solution can contain Clions or a mixture of SOand Clions.

Redox flow batteries based on supporting solutions containing chloride

A redox flow battery includes an anolyte storage tank configured for containing a quantity of anolyte and an anolyte headspace; a catholyte storage tank configured for containing a quantity of a catholyte and a catholyte headspace; and a gas management system comprising at least one conduit interconnecting the anolyte headspace and the catholyte headspace, and a gas exchange device configured to contain or release an evolving gas from either or both of the anolyte and catholyte storage tanks to an exterior battery environment when an interior battery pressure exceeds an exterior battery pressure by a predetermined amount.

Iron-sulfide redox flow battery (RFB) systems can be advantageous for energy storage, particularly when the electrolytes have pH values greater than 6. Such systems can exhibit excellent energy conversion efficiency and stability and can utilize low-cost materials that are relatively safer and more environmentally friendly. One example of an iron-sulfide RFB is characterized by a positive electrolyte that comprises Fe(III) and/or Fe(II) in a positive electrolyte supporting solution, a negative electrolyte that comprises Sand/or S in a negative electrolyte supporting solution, and a membrane, or a separator, that separates the positive electrolyte and electrode from the negative electrolyte and electrode.

Carbon monoxide (CO) is selectively reacted with hydrogen (H) over a ruthenium (Ru) on alumina catalyst at a temperature of about 210 to about 290&#xb0; C. To be a viable option for micro catalytic fuel processing devices, highly active, selective, and stable catalysts must be demonstrated with as large a temperature window for feasible operation as possible. We have studied the effects of metal loading, preparation method, pretreatment conditions, and choice of support on the performance of Ru-based catalysts for such applications. Catalyst testing results and catalyst characterization using XRD and BET are discussed. In one example, operating at a gas hourly space velocity (GHSV) of 13,500 hr, a 3% Ru/AlOcatalyst yielded CO outputs less than 100 ppm in a temperature range from 240&#xb0; C. to 285&#xb0; C., while not exceeding a hydrogen consumption of 10%. This catalyst was further successfully demonstrated in a microchannel device.

Selective CO methanation catalysis

A redox flow battery having a supporting solution that includes Clanions is characterized by an anolyte having Vand Vin the supporting solution, a catholyte having Feand Fein the supporting solution, and a membrane separating the anolyte and the catholyte. The anolyte and catholyte can have V cations and Fe cations, respectively, or the anolyte and catholyte can each contain both V and Fe cations in a mixture. Furthermore, the supporting solution can contain a mixture of SOand Clanions.

Fe-V redox flow batteries

Methods of the present invention can be used to synthesize nanowires with controllable compositions and/or with multiple elements. The methods can include coating solid powder granules, which comprise a first element, with a catalyst. The catalyst and the first element should form when heated a liquid, mixed phase having a eutectic or peritectic point. The granules, which have been coated with the catalyst, can then be heated to a temperature greater than or equal to the eutectic or peritectic point. During heating, a vapor source comprising the second element is introduced. The vapor source chemically interacts with the liquid, mixed phase to consume the first element and to induce condensation of a product that comprises the first and second elements in the form of a nanowire.
