Abstract

An electrode structure for a battery includes a middle layer made of an electrically conductive perforated mesh having a top surface, a bottom surface, a plurality of interconnected electrically conductive segments and a plurality of perforations among adjacent ones of the interconnected segments. A top layer of an electrode material is disposed on the top surface, and a bottom layer of the electrode material is disposed on the bottom surface, such that the top and bottom layers are disposed in physical contact with each other through the perforations in the middle layer. A method of manufacturing the electrode structure includes providing the layer of perforated mesh, applying the top and bottom layers of electrode material to the top and bottom surfaces, and curing the top and bottom layers of electrode material using one or more of heat, electromagnetic radiation and convection to produce a layer of cured electrode structure.
