Abstract

An electrochemical stack comprising carrier ions, an anode comprising an anode active material layer, a cathode comprising a cathode active material layer, a separator between the anode and the cathode comprising a porous dielectric material and a non-aqueous electrolyte, and an ionically permeable conductor layer located between the separator and an electrode active material layer.
