Claim 18:
19. A system for renovating a consumed anode in at least one metal-air cell without dismantling the cell, the system comprises:
a slurry return tube configured to circulate electrolyte through the cell to evacuate used slurry from the cell:
a fresh slurry supply tube configured to circulate electrolyte with fresh slurry into the cell and allowing sedimentation of the fresh slurry inside the cell to form an anode:
at least one pressurized layer positioned adjacent to the anode of the cell and configured to compact the fresh slurry to reduce gaps and increase conductivity between its particles, and further comprising:
at least one pressure sensor and/or at least one conductivity sensor configured to measure conductivity between the fresh slurry and a current collector of the cell, and
a pressure control means configured to control at least one of:
a compacting pressure applied by the at least one pressurized layer as measured by the at least one pressure sensor if implemented,
a cell volume, to compensate for a change in volume of the fresh slurry due to transformation thereof from metal to metal-oxide during operation of the metal-air cell, and
the conductivity across the fresh slurry, as measured by the at least one conductivity sensor when implemented, to compensate for a change in conductivity of the fresh slurry due to transformation thereof from conductive metal to non-conductive metal-oxide during operation of the metal-air cell.
