    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: A method of preparing a graphene-sulfur nanocomposite for a cathode in a rechargeable lithium-sulfur battery comprising thermally expanding graphite oxide to yield graphene layers, mixing the graphene layers with a first solution comprising sulfur and carbon disulfide, evaporating the carbon disulfide to yield a solid nanocomposite, and grinding the solid nanocomposite to yield the graphene-sulfur nanocomposite. Rechargeable-lithium-sulfur batteries having a cathode that includes a graphene-sulfur nanocomposite can exhibit improved characteristics. The graphene-sulfur nanocomposite can be characterized by graphene sheets with particles of sulfur adsorbed to the graphene sheets. The sulfur particles have an average diameter of less than 50 nm.

    Abstract: Magnesium energy storage devices that take advantage of magnesium-based anodes while maintaining practical energy densities can be useful for large-scale energy storage as well as other applications. One such device can include a negative electrode having magnesium and a positive electrode material that can flow in a batch or continuous manner. The flowable positive electrode material can result in an increased practical energy density because the fresh active material can be flowed to the positive electrode, and as a result can be theoretically infinite in size. The positive electrode can include a cathode suspension contacting a positive current collector and having particulates of a cathode magnesium intercalation compound, a cathode magnesium conversion compound, a redox active species, or combinations thereof.

    Abstract: Electrolytes for Mg-based energy storage devices can be formed from non-nucleophilic Mg2+ 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 Mg2+ electrolytes utilizes inexpensive and safe magnesium dihalides as non-nucleophilic Mg2+ sources in combination with Lewis acids, MRaX3-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 Mg2+ sources.
