TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Battery: The first and second solid electrolyte layers are electrically insulating. The first and second solid electrolyte layers are lithium ion conductive. The first solid electrolyte layer is deposited onto the anode and the second solid electrolyte layer is deposited onto the cathode by atomic layer deposition. The battery comprises a polymeric separator between the anode and the cathode. The first and second solid electrolyte layers electrically separate the anode and the cathode. The liquid electrolyte comprises a lithium salt in an organic solvent. The anode and cathode is preformed. The anode comprises an anode current collector. The cathode comprises a cathode current collector. The first and second solid electrolyte layers are deposited at a thickness of 1-5 microns. The anode is contacted with nitrogen dioxide and trimethyl aluminum prior to atomic layer deposition. The first and second solid electrolyte layers comprise a lithium oxide film and the atomic layer deposition involves contacting the anode and the cathode with lithium tert-butoxide and water. The first and second solid electrolyte layers comprise lithium lanthanum titanate.
