Patent number: 11616264Abstract: A method and system for creating low corrosion passivation layer on an anode in a metal-air cell comprise asserting high negative potential and low drawn current density on the cell after its operational parameters have stabilized after the cell has been powered-on. As a result the H2 evolution rate momentarily raises and then drops sharply, thereby causing the creation of a passivation layer on the face of the anode.Type: GrantFiled: June 30, 2021Date of Patent: March 28, 2023Assignee: Phinergy Ltd.Inventors: Ilya Yakupov, Avraham Yadgar, Aviel Danino

Patent number: 11611088Abstract: The invention relates to a metal-air electrochemical cell comprising a frame (100) defining an electrolyte chamber having an anode side and a cathode side, wherein an air cathode assembly is provided in the cathode side, said air cathode assembly (20) comprising hydrophobic porous film having a first face and a second face, with current collector (21) and catalyst-containing active layer (26) provided on said first face, with the planar dimensions of the catalyst-containing active layer on said first face being smaller than that of said hydrophobic film and said current collector, such that the catalyst-containing active layer does not reach the edges of said hydrophobic film and said current collector, thereby creating a catalyst-free margin (27) on the hydrophobic film (31) and current collector which surrounds the catalyst-containing active layer, and wherein said first face of the hydrophobic film and said frame of the cell arm joined together by thermoplastic (101) applied onto the catalyst-free margin oType: GrantFiled: June 6, 2019Date of Patent: March 21, 2023Assignee: OXENERGY LTD.Inventors: Yisrael Miler, Elad Shina, Aviel Danino, Irena Kobrin, Omri Feingold, Avi Melman, Joel Lang

Publication number: 20220045390Abstract: Methods and systems for electrolyte regeneration are provided, which regenerate a spent alkaline electrolyte (SE) comprising dissolved aluminum hydrates from an aluminum-air battery, by electrolysis, to precipitate aluminum tri-hydroxide (ATH) and form regenerated alkaline electrolyte, and adding a same-cation salt to an anolyte used in the electrolysis to supplant a corresponding electrolyte cation. The regeneration may be carried out continuously and further comprise mixing the SE and the same-cation salt in a salt tank configured to deliver the anolyte, removing the regenerated alkaline electrolyte from a catholyte tank configured to deliver the catholyte, and filtering the ATH from a solution delivered from the salt tank to the anolyte. Optionally, the salt may be a buffering salt, and in some cases chemical reactions may be used to enhance the regeneration by electrolysis.Type: ApplicationFiled: December 10, 2019Publication date: February 10, 2022Applicant: PHINERGY LTD.Inventors: Ilya YAKUPOV, Aviel DANINO, Mark WEAVER, Sean Henry GALLAGHER, Nicola MENEGAZZO

Publication number: 20220029248Abstract: Rechargeable batteries and corresponding methods are provided, in which zinc dendrite growth to a compartment between a zinc-based anode and a separator of a rechargeable battery is limited, by preventing zincate anions from diffusing outside of the compartment. Separators limiting dendrite growth may comprise ion-selective membrane(s) configured to be permeable to charge transfer cations of the alkaline electrolyte and impermeable to hydrated zincate anions. The membrane(s) may be reinforced and/or support internal compartment(s) with electrolyte lacking zincate ions. More generally, separators are provided, which are permeable to charge transfer ions but impermeable to metal ions, and limit the latter to the anode compartment in which the metal ions may be deposited in a manner that does not form dendrites which can compromise the structural and functional integrity of the battery cell.Type: ApplicationFiled: December 3, 2019Publication date: January 27, 2022Applicant: PHINERGY LTD.Inventors: Aviel DANINO, Ilya YAKUPOV
