摘要： A system and method for measuring the state of charge (SOC), molarity and concentrations of active species and oxidation state of a flow battery, such as a Vanadium Redox Flow Battery (VRFB). A reference electrolyte is circulated through a reference cell in conjunction with one or both charged electrolytes (in respective conduits). The electric potential of charged electrolyte relative to a reference electrolyte is measured. This measurement is directly convertible to SOC. An equation allowing for the calculation of the molarity, concentration of vanadium ions on both anolyte and catholyte sides of the flow battery and oxidation state is also taught. A flow battery may be controlled in response to such a determination, for example to manage oxidation state, or to charge or discharge a battery.

摘要： A modular flow battery includes a battery stack container housing a plurality of redox flow battery stacks in fluid communication with at least one pair of electrolyte containers including an anolyte container for holding an anolyte and a catholyte container for holding a catholyte. Additional pairs of electrolyte containers can be connected to the battery stack container to increase an amount of energy that can be stored by the modular flow battery system. Respective housings enclosing each of the battery stack container and the electrolyte containers are configured for operation in a stacked configuration. In this manner, the energy storage capacity of the modular flow battery system can be further increased with substantially no increase in a lateral area occupied by the system.

摘要： Methods and systems for removing impurities from electrolyte solutions having three or more valence states. In some embodiments, a method includes electrochemically reducing an electrolyte solution to lower its valence state to a level that causes impurities to precipitate out of the electrolyte solution and then filtering the precipitate(s) out of the electrolyte solution. In embodiments in which the electrolyte solution is desired to be at a valence state higher than the precipitation valence state, a method of the disclosure includes oxidizing the purified electrolyte solution to the target valence.

摘要： A flow battery system can include at least one pair of electrolyte storage, a first battery stack, and a second battery stack. The electrolyte storage pair can include an anolyte storage configured to contain an anolyte solution, and a catholyte storage configured to contain a catholyte solution. The first battery stack can be fluid communication with the electrolyte storage pair. The first battery stack can also be configured to receive electrical energy from a power source and to facilitate redox reactions storing the received electrical power as chemical energy by the anolyte and catholyte solutions. The second battery stack can be in fluid communication with the at least one pair of electrolyte storage. The second battery stack can also be configured to supply electrical energy to an electrical load, and to facilitate redox reactions releasing chemical energy stored by the anolyte and catholyte solutions as electrical energy to the load.
