ABSTRACT:
A sheetlike laminated air cathode including first and second layers having opposed major surfaces respectively exposed for contact with a liquid electrolyte and with air, the layers also having facing major surfaces, and the second layer being permeable to air but not to the liquid electrolyte; and a current collector in contact with the first layer and connectable to external electrical circuitry. The first layer is a nonwoven fibrous web impregnated with a mixture of carbon particles and a nonfibrous polymeric substance for holding the carbon particles in the web. The facing major surfaces of the first and second layers are bonded together by heat seal coating material distributed on those major surfaces in such manner as to provide an array or network of areas free of coating material extending substantially uniformly thereover.
