    摘要： 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.

    摘要： 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.

    摘要： This invention relates to the regeneration of spent alkaline solutions, for example, alkaline electrolyte solutions used in metal/air batteries, specifically in aluminum/air batteries. The invention provides methods and systems to regenerate alkaline electrolyte solutions by adding water and optionally other solvents to spent electrolyte solutions, thus precipitating metal hydroxides from the spent electrolyte solution.
