    Abstract: RFBs having solid hybrid electrodes can address at least the problems of active material consumption, electrode passivation, and metal electrode dendrite growth that can be characteristic of traditional batteries, especially those operating at high current densities. The RFBs each have a first half cell containing a first redox couple dissolved in a solution or contained in a suspension. The solution or suspension can flow from a reservoir to the first half cell. A second half cell contains the solid hybrid electrode, which has a first electrode connected to a second electrode, thereby resulting in an equipotential between the first and second electrodes. The first and second half cells are separated by a separator or membrane.

    Abstract: Nanostructured bismuth materials can be utilized as an insertion material in electrodes for magnesium energy storage devices to take advantage of short diffusion lengths for Mg 2+ . The result can be a significantly increased charge/discharge rates and/or improved cycling stabilities. In one example, an energy storage device has magnesium as an electroactive species, an electrolyte salt containing magnesium, and an anode having bismuth nanostructures. The bismuth nanostructures have at least one dimension that is less than or equal to 25 nm. At least a portion of the magnesium is reversibly inserted into, and extracted from, the anode during discharging and charging states, respectively.

    Abstract: Electrolytes for Mg-based energy storage devices can be formed from non-nucleophilic Mg 2+ sources to provide outstanding electrochemical performance and improved electrophilic susceptibility compared to electrolytes employing nucleophilic sources. The instant electrolytes are characterized by high oxidation stability (up to 3.4 V vs Mg), improved electrophile compatibility and electrochemical reversibility (up to 100% coulombic efficiency). Synthesis of the Mg 2+ electrolytes utilizes inexpensive and safe magnesium dihalides as non-nucleophilic Mg 2+ sources in combination with Lewis acids, MR a X 3-a (for 3≥ a≥ 1). Furthermore, addition of free-halide-anion donors can improve the coulombic efficiency of Mg electrolytes from nucleophilic or non-nucleophilic Mg 2+ sources.

    Abstract: The performance of sodium-based energy storage devices can be improved according to methods and devices based on surface-driven reactions between sodium ions and functional groups attached to surfaces of the cathode. The cathode substrate, which includes a conductive material, can provide high electron conductivity while the surface functional groups can provide reaction sites to store sodium ions. During discharge cycles, sodium ions will bind to the surface functional groups. During charge cycles, the sodium ions will be released from the surface functional groups. The surface-driven reactions are preferred compared to intercalation reactions.
