摘要： Rechargeable batteries include a NiyFe1-y cathode where 0≤y≤1, an anode comprising a current collector, a porous separator positioned between the cathode and the anode, and an electrolyte comprising MAlX4, wherein M is Na, Li, K, or a combination thereof, and X is Cl, Br, I, or a combination thereof, and wherein the electrolyte is a solid at temperatures less than 50° C. The batteries are temperature activated. The electrolyte temperature is increased above its melting point while charging and reduced below the melting point for energy storage, such as seasonal energy storage. The electrolyte temperature is increased above the melting point again to discharge the battery.

摘要： Indium zinc-based alloy anodes include an InxMyZnz alloy, where x ranges from 0.03 to 0.20, z ranges from 0.80 to 0.97, and x+y+z=1 when the anode has not previously been cycled. M is Al, Ag, Bi, Sn, Cd, or any combination thereof. In a partially or fully discharged state after one or more cycles, the anode includes a porous surface portion enriched in indium and a bulk portion comprising the InxMyZnz alloy. In a subsequent partially or fully charged state, the pores may be at least partially filled with zinc.

摘要： A reference electrode assembly includes a reference electrode, a counter electrode, and a variable resistor. The reference electrode comprises a foil of a first metal or a foil coated with the first metal, has a width ≥0.5 mm and a length ≥the width. A surface of the reference electrode has an average roughness (Ra)≤1 μm. The counter electrode comprises a foil of a second metal or a foil coated with the second metal. The reference and counter electrodes are spaced apart. The reference electrode is configured to be electrically coupled directly or indirectly to a (−) power terminal of an external power source, and the counter electrode is configured to be electrically coupled directly or indirectly to a (+) power terminal of the external power source. The variable resistor is positioned between the external power source and either the counter electrode or the reference electrode.

摘要： A redox flow battery stack cell frame comprising a support frame and a monolithic bipolar plate integrated within the support frame is disclosed. The bipolar plate comprises a plurality of interdigitated flow channels on at least one surface. The support frame comprises an inlet manifold formed into a facing surface of the first side of the frame, the inlet manifold comprising fluid inlet distribution channels in a serpentine arrangement, each fluid inlet distribution channel aligned with a single inlet flow channel of the bipolar plate; and an outlet manifold formed into the facing surface of the opposing side of the frame, the outlet manifold comprising fluid outlet distribution channels in a serpentine arrangement, each fluid outlet distribution channel aligned with a single outlet flow channel of the bipolar plate. Redox flow battery stack cells and stacks comprising the stack cell frame are also disclosed.

摘要： The current invention is a composite material and a method for making a material that changes an optical characteristic by utilizing the temperature dependent intrinsic properties of at least two phases in the composite. With changes in temperature, these composites become translucent due to the refractive index mismatch that is accompanied by interfacial light scattering.
