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: Conducting coatings disposed on a metal member. The conducting coatings may have a desired texture and provide homoepitaxial or heteroepitaxial coating of an electrodeposited layer. A conducting coating may be formed by applying a shear force during deposition of the conducting coating. The conducting coatings may be used in anodes of various electrochemical devices. A conducting coating, which may be part of an electrochemical device, may have an electrochemically deposited layer disposed on at least a portion of a surface of the conducting coating. The electrochemically deposited layer may be reversibly electrochemically deposited.

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: Provided are passivation layers for batteries. The batteries may be aqueous aluminum batteries. The passivation layer may be disposed on a portion of or all of a surface or surfaces of an anode, which may be an aluminum or aluminum alloy anode. The passivation layer is bonded to the surface of the anode. The passivation layer may be an organic, nitrogen-rich material and inorganic Al-halide rich or Al-nitrate rich material. The passivation layer may be formed by contacting an aluminum or aluminum alloy substrate, which may be aluminum or aluminum alloy anode, with one or more aluminum halide and one or more ionic liquid.
