Abstract
A textured dual layer metal air cathode is disclosed. The cathode includes a first layer that contains 30% to 70% organic polymer by weight, a second layer that contains 10% to 30% organic polymer by weight, and a catalyst. The first layer and the second layer contact each other at a textured interface.
