Abstract

An electrochemical cell includes a cathode, an anode, an electrolyte located between the cathode and the anode, an anode current collector and a cathode current collector, wherein at least one of the anode and cathode is a three dimensional (3D) porous structure including ionically conducting electrolyte strands extending through the porous structure from the corresponding current collector to the electrolyte separator, pores extending through the porous structure from the corresponding current collector to the electrolyte separator, and an electronically conducting network extending on sidewall surfaces of the pores from the corresponding current collector to the electrolyte separator.
