A system and method for forming a metallic ion intercalated layered structure can include a housing, an electrolyte disposed in the housing, a counter-electrode disposed in the housing, and a working electrode disposed in the housing. The working electrode comprises a metallic support; and an electrode paste. The electrode paste can include an active material and a binder. The system can be used to form a layered structure having metallic ions from the metallic support intercalated into the layered structure based on cycling the working electrode.

Metallic ion intercalated layered structures

A battery includes a cathode compartment, a catholyte solution disposed within the cathode compartment, an anode compartment, an anolyte solution disposed within the anode compartment, a separator disposed between the cathode compartment and the anode compartment, and a flow system configured to provide fluid circulation in the cathode compartment and the anode compartment. The catholyte solution and the anolyte solution have different compositions.

High-voltage ion-mediated flow/flow-assist manganese dioxide-zinc battery

A zinc electrode comprises an anode material, the anode material comprising: an electroactive material comprising at least one of zinc or a compound comprising zinc, a stabilizer additive comprising at least one of: bismuth, copper, indium, a compound comprising bismuth, a compound comprising copper, a compound comprising indium, or any combination thereof, a conductive additive, and a binder.

Zinc electrodes with high capacity utilizations

A method of forming a layered manganese dioxide for use in a cathode of a battery comprises disposing a cathode into a housing of an electrochemical cell, disposing an anode into the housing, disposing a polymeric separator between the anode and the cathode such that the anode and the cathode are electrically separated, adding an alkaline electrolyte to the housing, cycling the electrochemical cell into the 2electron capacity of the manganese dioxide, and forming a layered manganese dioxide having a layered manganese dioxide structure with the one or more additives incorporated into the layered manganese dioxide structure. The cathode comprising a cathode material comprising: a manganese dioxide compound, one or more additives selected from the group consisting of bismuth, copper, tin, lead, silver, cobalt, nickel, magnesium, aluminum, potassium, lithium, calcium, gold, antimony, iron, zinc, and combinations thereof, and a conductive carbon.

Process for making manganese dioxide and its polymorphs reversible

A rechargeable battery can include a cathode, an anode current collector, an anode comprising zinc, and an electrolyte in ionic communication with both the cathode and the anode current collector. The electrolyte can include an organic ammonium halide. The organic ammonium halide can include an ammonium bromide in some instances.
