Title: Method for manufacturing three dimensional electrode elements for micro-batteries

Abstract: A method for forming an array of three dimensional electrode elements for micro-batteries, including forming a plurality of first parallel channels in a substrate, filling the plurality of first channels with a sacrificial filler material, forming at least one plurality of second parallel channels, each of the pluralities of channels being oriented in a different direction, and removing the sacrificial filler material to leave a grid array of electrode elements. The method may further include a preliminary step of depositing a sacrificial coating onto the surface of the substrate and a final step of removing the sacrificial coating and any debris resulting from the channel forming steps deposited thereon.
