Abstract
An electrochemical cell is provided which includes a cathode, an anode, an electrolyte separator, and an anode current collector located on the anode. The anode is a three-dimensional (3D) porous anode including ionically conducting electrolyte strands and pores which extend through the anode from the anode current collector to the electrolyte separator. The anode also includes electronically conducting networks extending on sidewall surfaces of the pores from the anode current collector to the electrolyte separator.
