PROTECTED LITHIUM ELECTRODES WITH PROTECTIVE MEMBRANE HAVING A GARNET LIKE STRUCTURE AND LITHIUM BATTERY CELLS THEREOF

摘要

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.
