  • SYSTEM ENERGY DENSITY IN A REDOX FLOW BATTERY
    Publication number: 20160006051
    Abstract: A redox flow battery (RFB) controllable by a battery management system and having an energy output has a volume of at least 2000 liters and an energy density of at least 10 w-h/liter. In one embodiment, the RFB maintains at an energy density of at least 10 w-h/liter for a minimum of 50 continuous full charge/discharge cycles or the equivalent number of operating hours without user input.

  • METHODS FOR DETERMINING AND/OR ADJUSTING REDOX-ACTIVE ELEMENT CONCENTRATIONS IN REDOX FLOW BATTERIES
    Publication number: 20150303504
    Abstract: Methods of determining concentrations and/or amounts of redox-active elements at each valence state in an electrolyte solution of a redox flow battery are provided. Once determined, the concentrations and/or amounts of the redox-active elements at each valence state can be used to determine side-reactions, make chemical adjustments, periodically monitor battery capacity, adjust performance, or to otherwise determine a baseline concentration of the redox-active ions for any purpose.

  • ELECTROLYTE PROTECTION COMPOSITIONS AND METHODS
    Publication number: 20140272482
    Abstract: A barrier on the surface of the negative electrolyte solution of a redox flow battery can decrease air oxidation of a charged species in the negative electrolyte solution and can decrease water loss from the negative electrolyte solution. A negative electrolyte tank including a barrier on the surface of the negative electrolyte can have many advantages, including simplified setup, low cost, and low maintenance.
