Abstract: A method for preparation of electrolyte for a redox flow battery includes reducing chromium ore using a carbon source to convert the chromium ore to an iron/chromium alloy with carbon particles; dissolving the iron/chromium alloy with carbon particles in sulfuric acid to form a first solution; adding calcium chloride or barium chloride to the first solution to produce a second solution including FeCl3 and CrCl3; and adding an acid to the second solution to form the electrolyte. Other methods can be used for preparing an electrolyte from chromium waste material.

Abstract: Described herein are, inter alia, electrodes for use in energy storage devices, such as a cathode or anode in a battery. An electrode may include a substrate which serves as a reaction site that occur during electrochemical cycling of an energy storage device. In some embodiments, an electrode can undergo intercalation chemistry, conversion chemistry, plating-stripping/deposition-dissolution chemistry, or combinations thereof. A film and/or additive may be provided in an electrode in order to mitigate side reactions and/or electrochemical passivation reactions. An electrode may include one or more materials that (i) electrochemically reduce a portion of the electrolyte to a gas during electrochemical cycling, (ii) suppress generation of hydrogen gas by increasing a hydrogen evolution overpotential, (iii) constrain gas after formation, and/or (iv) catalyze oxidation of a gas back into an electrolyte. An electrode may include one or more electroactive materials in addition to a substrate.

Abstract: One embodiment is a redox flow battery system that includes an anolyte; a catholyte; an anolyte tank configured for holding at least a portion of the anolyte; a catholyte tank configured for holding at least a portion of the catholyte; a primary redox flow battery arrangement, and a second redox flow battery arrangement. The primary and secondary redox flow battery arrangements share the anolyte and catholyte tanks and each includes a first half-cell including a first electrode in contact with the anolyte, a second half-cell including a second electrode in contact with the catholyte, a separator separating the first half-cell from the second half-cell, an anolyte pump, and a catholyte pump. The peak power delivery capacity of the secondary redox flow battery arrangement is less than the peak power delivery capacity of the primary redox flow battery arrangement.

Abstract: Dual-functional energy storage systems that couple ion extraction and recovery with energy storage and release are provided. The dual-functional energy storage systems use ion-extraction and ion-recovery as charging processes. As the energy used for the ion extraction and ion recovery processes is not consumed, but rather stored in the system through the charging process, and the majority of the energy stored during charging can be recovered during discharging, the dual-functional energy storage systems perform useful functions, such as solution desalination or lithium-ion recovery with a minimal energy input, while storing and releasing energy like a conventional energy storage system.

Abstract: The application relates to battery materials, and particularly discloses a method for preparing vanadium electrolyte for an all-vanadium redox flow battery. An example method includes: heating high-purity vanadium pentoxide, and reducing the high-purity vanadium pentoxide by using a reducing gas to obtain a low-valence vanadium oxide; mixing low-valence vanadium oxide with an activating agent, and heating and activating to obtain vanadium-containing paste electrolyte; and adding water to dissolve the vanadium-containing paste electrolyte to obtain the vanadium electrolyte with the average valence of vanadium between positive three and positive four. Compared with a finished product vanadium electrolyte, the vanadium-containing paste electrolyte is small in size, and the sulfuric acid is solidified, so that the corrosion of the sulfuric acid to a container can be reduced, the cost for transporting the vanadium-containing paste electrolyte is lower than the cost for directly transporting the vanadium electrolyte, and the vanadium electrolyte is promoted.
