ABSTRACT:
An air electrode, for use in electrochemical energy cells, is made, comprising a multi-layer hydrophilic section, consisting of at least two substantially uncompacted laminated layers of plaques cntaining loaded, catalytically active battery material; each loaded plaque consisting of a 75% porous to 95% porous metal current collector, having between about 45% to about 95% of its pore volume filled with the active material, where the weight ratio of active material:plaque current collector in the laminated layers is between 0.40:1 and 2.80:1.
