TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The separator further comprises a ceramic having a first surface and second surface, and the separator is disposed in the lithium-air battery, where the first surface is proximal to the lithium anode, and the second surface is proximal to the air cathode. The separator comprises: an interpenetrating network polymer comprising the crosslinked polysiloxane and a second, crosslinked polymer, where the second, crosslinked polymer comprises a poly(meth)acrylate, polyolefin, or polyurethane; and a film of the crosslinked polysiloxane and a film of a second, crosslinked polymer, where the films are laminated together. The air cathode comprises a porous carbon material. The air cathode further comprises a metal oxide, or a binder. The air cathode consists essentially of a porous carbon material, a catalyst of manganese dioxide, a polymer binder of polyvinylidene difluoride, and a current collector.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The separator is a coating on a surface of the lithium anode. The ceramic comprises a glass or lithium-aluminum-silicon phosphorus oxide compound of formula (Li(1+x+y)Alx(Ti,Ge)(2-x)SiyP(3-y)O12).x = 0-0.4; andy = greater than 0 and less than or equal to 0.6.The ceramic is lithium oxide-aluminum oxide-silicon dioxide-phosphorus pentoxide- titanium dioxide germanium dioxide.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The coating comprises at least one layer of the crosslinked polysiloxane on the surface of the lithium anode. The crosslinker is substituted hydrocarbon compounds of formula (CH=CH-CH2O(CH2-CH2O)q-CH2CH=CH2) or (R2C=CR3C(O)(OCH2CHX)nE1C(O)CR4=CR5). The olefinic polyethylene oxide is of formula (CH=CH-CH2O(CH2-CH2O)p-CH3). The polysiloxane comprising silicon-hydrogen groups is of formula (-(Si(R1)(H)O)m-).R2, R5 = H or 1-12C;R3, R4 = H, 1-12C alkyl, or 2-12C alkenyl;X = H or CH3,E1 = CH2 or O;n, q, p = 1-15;R1 = H or 1-12C alkyl; andm = 3-13.Preferred Process: The crosslinked polysiloxane is laminated to the first surface in layers of the crosslinked polysiloxane. The process further comprises: laminating the crosslinked polysiloxane to a second polymeric material, where the second polymeric material is a poly(meth)acrylate, polyolefin, or polyurethane; coating a lithium anode with the polymerization mixture prior to heating; coating at least one surface of a ceramic separator with the crosslinked polysiloxane; and coating at least one surface of a ceramic separator with the polymerization mixture prior to heating.
