Patent number: 11552302Abstract: A method for forming a melamine-modified electrode that includes providing a metal based electrode and patterning a surface of the metal-based electrode by contacting the electrode with a melamine solution to form a patterned metal-based electrode. The patterned metal-based electrode includes metal sites blocked with melamine molecules and metal sites which are not blocked such that the metal-based electrode selectively adsorbs O2 instead of at least one of sulfate, phosphate, or sulphonate. A range of 20% to 40% of the metal sites are blocked with melamine molecules.Type: GrantFiled: September 21, 2021Date of Patent: January 10, 2023Assignee: UChicago Argonne, LLCInventors: Dusan Strmcnik, Pedro Farinazzo Bergamo Dias Martins, Milena Zorko, Haifeng Lv, Vojislav Stamenkovic

Patent number: 11121402Abstract: An alternative grid energy storage system is described herein. In one embodiment, an electrochemical cell comprises a high specific surface area cathode (e.g., a cathode comprising a carbon nanofoam paper, a carbon nanotube mesh, a particulate carbon material, electrolytic manganese dioxide, or a manganese dioxide film), a zinc or lead anode (e.g., Zn or Pb foil), a selective ion-conductive separator that does not conduct zinc ions (e.g., a NAFION sulfonated tetrafluoroethylene based fluoropolymer-copolymer separator) between the anode and the cathode, and an aqueous electrolyte comprising a manganese salt (e.g., aqueous manganese sulfate) contacting the electrodes and the separator. A battery comprising two or more of the electrochemical cells electrically connected together in series, parallel, or both, also is described.Type: GrantFiled: January 31, 2020Date of Patent: September 14, 2021Assignee: UChicago Argonne, LLCInventors: Sanja Tepavcevic, Nigel Hajj Becknell, Pietro Papa Lopes, Dusan Strmcnik, Vojislav Stamenkovic
