Title: Lithium-oxygen (AIR) electrochemical cells and batteries

Abstract

This invention provides a lithium-oxygen or lithium-air electrochemical cell comprising a negative electrode, an electrolyte, and a porous activated positive electrode comprising lithium-rich electrocatalytic materials suitable for use in lithium-oxygen (air) cells and batteries. The activated positive electrode is produced by activating a precursor electrode formed from a material comprising one or more metal oxide compounds of general formula xLi2O.yMOz, in which 0
