A rechargeable non-aqueous lithium-air battery is provided having a multilayered cathode structure which uses a functionized carbon paper base with tubular catalysts. The multilayer cathode has a sufficient pore size to prevent clogging of the cathode by reaction products and further has a hydrophobic coating to repel moisture. The stable electrolyte is made by ionic liquid and additives which have no reaction with discharge products and offers solubility for oxygen and lithium oxide.
