Abstract: Rechargeable batteries are disclosed having a protective membrane layer on surfaces of an electrode such as cathode active material. Such membranes include anionically charged groups and include an anionic membrane or a zwitterionic membrane. Such membranes can minimize contact of electrolyte to the surfaces of the active materials of the cathode where oxidation of electrolyte typically occurs thus promoting thermal stability of the electrolyte especially for high voltage batteries.

Abstract: Hybrid electrodes for batteries are disclosed having a protective electrochemically active layer on a metal layer. Other hybrid electrodes include a silicon salt on a metal electrode. The protective layer can be formed directly from the reaction between the metal electrode and a metal salt in a pre-treatment solution and/or from a reaction of the metal salt added in an electrolyte so that the protective layer can be formed in situ during battery formation cycles.

Abstract: Rechargeable metal batteries are disclosed having a protective ionic membrane layer on a metal anode. The ionic membrane can be formed from ionomers in the electrolyte including polymerizable ionic liquid monomers or halogenated alkyl anion salts. Such ionic membranes can continuously supply ions near the anode electrode and stabilize the anode metal electrode.
