    Abstract: A method for renovation of a consumed anode in a metal-air cell without dismantling the cell according to embodiments of the present invention comprising 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.

    Abstract: Aluminum-air battery units and stacks are provided with frames configured to mechanically support the anode of each unit, within a housing configured to support the frame and the air cathode(s) mechanically, sealably hold the electrolyte within the housing and in fluid communication with openings in the housing—forming one or two sided electrochemical cell in each unit. The frame comprises a protective strap configured to protect edges of the rectangular anode against corrosion by the electrolyte during operation, and also an external trapezoid shape that is configured to press the protective strap against the edges of the rectangular anode upon insertion of the frame with the anode into the housing. Various embodiments comprise, spacers between the anode and cathodes and grids supporting airways to the cathodes. In disclosed configurations, anode may be replaced after electrolyte evacuation while maintaining the stack sealed and quickly ready for renewed operation.
