POUCHED METAL-AIR BATTERY CELLS

A metal-air battery cell includes an electrode assembly and a sealed pouch. The electrode assembly includes an air electrode, a negative electrode, a separator in contact with and disposed between the electrodes, and a hydrophobic gas diffusion layer in contact with a side of the air electrode opposite the separator. The pouch envelops the electrode assembly and contains an electrolyte therein. The pouch is defined by a gas permeable hydrophobic flexible layer in contact with the hydrophobic gas diffusion layer. The electrode assembly further includes a terminal extending from and away at least one of the electrodes, and through the pouch. Opposing sides of the pouch are sealed to each other and around the terminal.
