    摘要： A method for renovation of a consumed anode in a metal-air cell without dismantling the cell comprises circulating electrolyte through the cell to evacuate used slurry from the cell, circulating electrolyte with fresh slurry into the cell and allowing sedimentation of the fresh slurry inside the cell to form an anode and compacting the slurry to reduce the gaps between its particles. A meta-air cell enabling renovation of a consumed anode without dismantling the cell defining first outer face of the cell, air cathode layer adjacent the porous wall, separator wall disposed on the inner face of the air cathode layer, cell space volume to contain electrolyte and metal granules slurry, current collector layer to form an anode, made of current conductive material disposed in the space and flexible wall defining a second outer face of the cell wherein the flexible wall is adapted to be pushed towards inside of the cell subject to pressure applied to its outer face, thereby to reduce the volume of the space.

    摘要： Flow directing element in a metal air cell is configured to cause evenly distributed flow of aqueous electrolyte solution electrolyte in it over the anode. Flow distributing element in a metal air cell is configured to lengthen the path of electrolyte flow from an inlet to the anode, thereby to increase ohmic resistance to shunt currents in the cell. A battery with these cells consumes the metal in the metal anodes evenly and with minimized shunt currents.

    摘要： Methods and systems are provided, which convert spent electrolyte from aluminum-air batteries into high purity alumina (HPA) and useful co-products such as fertilizer(s) and/or feed supplement(s). Aluminum tri-hydroxide (ATH) having potassium (K) and/or sodium (Na) impurities, e.g., from spent electrolyte, may be dissolved in strong acid to form an acidic ATH solution having pH 4 to precipitate ATH while retaining dissolved K/Na in the neutralized solution. The dissolving and the neutralizing may then be repeated with the precipitated ATH until a specified purity level of the precipitated ATH is reached. Using appropriate bases to neutralize the acidic ATH solution, e.g., ammonia and/or choline, yields useful co-products such as ammonium nitrate (with nitric acid as the strong acid) and choline chloride (with hydrochloric acid as the strong acid), respectively.
