A rechargeable lithium metal cell

Abstract

The invention provides a rechargeable lithium metal cell, comprising: an anode comprising lithium metal; a cathode comprising a high-voltage cathode material; and a plurality of lithium-conductive layers interposed between the anode and the cathode, the lithium-conductive layers comprising a solid polymeric anolyte layer adjacent the anode and one or more further electrolyte layers which space apart the polymeric anolyte layer from the cathode, wherein the solid polymeric anolyte layer comprises (i) a block copolymer comprising at least one hydrophobic non-ionic block and at least one ionic block, and (ii) lithium salt, and wherein the solid polymeric anolyte layer has at least two glass transition temperature (Tg) values.
