Abstract
Electrodes having an active region formed of a plurality of layers in which one or more conductive layers is formed of a pattern having a plurality of branches and/or holes (e.g. a grid pattern, a snowflake pattern, etc.) to provide a greater density of edges, so that the ratio of edges in the patterned conductive layer to the perimeter of the active region is greater than a minimum value (e.g., 1.5, 2, 3, 4, 5, 6, etc.). The multiple layers may include the patterned conductive layer and a second conductive layer, which may also be patterned, with a less conductive layer sandwiched between them to achieve a more even charge distribution across the face of the active region than in addition to the greater current density provided by the large number of edges.
