Metal-oxygen cell comprises electrolyte consisting of porous part that is impregnated with electrolyte at the anode and ion exchange material at the cathode, and that limits build up of carbonates at cathode-electrolyte interface

摘要

A metal-oxygen cell comprising at least one cell consisting of a metallic anode and an oxygen cathode located on either side of an electrolyte comprising a first zone consisting of a porous part impregnated with liquid electrolyte comprising OH- anions and cations and a second zone comprising an OH- anion exchange material capable of limiting the passage of cations from the electrolyte. Independent claims are included for a method of obtaining the described electrolyte by impregnating the porous part and assembling with the second part and for a method starting from one material in which the porous part of the first zone and the second zone are created by phase inversion or by coagulation.
