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

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

Publication number: 20210399383Abstract: Separators, electrochemical cells and methods are provided, to improve operation of cells such as metal-ion batteries and fuel cells. Separators comprise a porous, ionically conductive film including layered double hydroxide(s) (LDHs), which are functional ceramic additives, removing potentially harmful anions from the electrolyte by incorporating them into the LDH structure of positively-charged sheets with intermediary anions. For example, anions which are electrolyte decomposition products or cathode dissolution products may be absorbed into the LDH to prevent them from causing damage to the cell and shortening the cell's life. LDHs may be incorporated in the separator structure, coated thereupon or otherwise associated therewith. Additional benefits include dimensional stability during thermal excursions, fire retardancy and impurity scavenging.Type: ApplicationFiled: November 6, 2019Publication date: December 23, 2021Applicant: PHINERGY LTD.Inventors: Ilya YAKUPOV, Nicola MENEGAZZO, Mark WEAVER

Patent number: 10608288Abstract: The present invention relates to safety methods and mechanisms for treating electrolyte solutions in batteries, specifically metal-air batteries. Systems and methods of the invention protect the battery, protect the battery operator and protect the environment from potential material hazards. This invention provides materials for arresting a potentially hazardous electrolyte solution by forming solid or gel porous polymer structures. The polymer porous structures consume or confine the electrolyte solution thus preventing its hazardous potential.Type: GrantFiled: April 13, 2015Date of Patent: March 31, 2020Assignee: PHINERGY LTD.Inventors: Aviv Tzidon, Dekel Tzidon, Avraham Yadgar, Ilya Yakupov
