Abstract
An electrode includes a current collector having metallic struts formed by freeze tape casting along a cast direction, and an electrochemically active material occupying portions of the void spaces. The struts define a percolated conductive network and void spaces through the percolated conductive network. The struts are directionally aligned and the void spaces are directionally ordered perpendicular to the cast direction.
