Abstract
Official abstract text for this publication.
Li/air battery cells are configurable to achieve very high energy density. The cells include a protected a lithium metal or alloy anode and an aqueous catholyte in a cathode compartment. In addition to the aqueous catholyte, components of the cathode compartment include an air cathode (e.g., oxygen electrode) and a variety of other possible elements.
First claim

1 . A protected lithium electrode comprising: a lithium anode, and a protective membrane architecture, comprising, a substantially impervious lithium ion conducting membrane having a first and second surface, the membrane comprising a lithium ion conducting oxide having a garnet like structure. 2 . The protected lithium electrode of claim 1 wherein the lithium anode is lithium metal. 3 . The protected lithium electrode of claim 1 wherein the lithium anode is a lithium metal alloy. 4 . The protected lithium electrode of claim 1 wherein the lithium anode is a lithium intercalation material. 5 . The protected lithium electrode of claim 1 wherein the oxide having a garnet-like structure comprising Zr as an elemental constituent. 6 . The protected lithium electrode of claim 1 wherein the mole ratio of Li/O in the oxide having a garnet-like structure is selected from the group consisting of 7/12, 6/12 and 5/12. 7 . The protected lithium electrode of claim 1 wherein the oxide having a garnet-like structure is Li 7 La 3 Zr 2 O 12 . 8 . The protected lithium electrode of claim 1 wherein the membrane first surface directly contacts the lithium metal anode. 9 . The protected lithium electrode of claim 1 wherein the lithium metal anode comprises lithium metal. 10 . A battery cell comprising the protected lithium electrode of claim 1 combined with a cathode compartment. 11 . The battery cell of claim 10 wherein the cathode compartment comprises a liquid electrolyte that does not contact the lithium anode.
