US 2026/0066397 A1 · ANODE FORMATION IN METAL-AIR CELLS

Abstract

Metal-air cells, battery stacks, battery system and methods of forming the anodes within the metalair cells without dismantling the cell are provided. The anodes include metal mesh(es) as current collector(s) and concentrated slurry comprising metal granules suspended in electrolyte, in electrical contact with the current collector(s). The concentration of the slurry is carried out by circulating it through a cell space between cathode(s) and the metal mesh(es), which are configured to increase the concentration of the metal granules accumulating thereupon. The rise in required circulation pressure (or the corresponding time period and/or changes in conductivity related thereto) is used to indicate the completion of the anode formation process. One- and two-dimensional implementations of cells are provided, and discharging efficiency may be enhanced by circulating the electrolyte during discharging.

Dependent claims

A metal-air cell comprising:

at least one air cathode with at least one associated separator, and
at least one anode comprising:
at least one current collector comprising at least one metal mesh, and
a concentrated slurry comprising metal granules suspended in electrolyte that is accumulated within a cell space volume defined between the at least one separator associated with the at least one air cathode and the at least one current collector, the concentrated slurry being in electrical contact with the at least one current collector and the cell space volume being in fluid communication with a slurry entrance, and, through the metal mesh, in fluid communication with a filtrate exit.
