Metal-air cells with minimal air access

Abstract

The present technology provides a battery that includes an air cathode, an anode, an aqueous electrolyte that includes an amphoteric surfactant, and a housing that includes one or more air access ports defining a total area of void space (“vent area”), where (1) the battery is a size 13 metal-air battery and the total vent area defined by all of the air access ports is from about 0.050 mm2 to about 0.115 mm2; or (2) the battery is a size 312 metal-air battery and the total vent area defined by all of the air access ports is from about 0.03 mm2 to about 0.08 mm2.

Dependencies are inferred from the claim text.
