A current collector comprising a frame conductor formed as a closed undulating perimeter, and a conductive mesh formed within the frame conductor is described. The conductive mesh is comprised of a plurality of radial struts, each radial strut having a central end and an outer end. The radial struts emanate from a junction within the undulating perimeter with their outer ends connected to the undulating perimeter of the frame. The conductive mesh may include branch struts having proximal ends and distal ends, with the proximal ends connected to the radial struts. The distal ends of the branch struts may be connected to the undulating perimeter, or to adjacent radial struts. The current collector is used in an electrochemical cell, wherein a first electrode active material is contacted to at least one of first and second major sides of the current collector to provide a first electrode.
