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: In various examples, an anode, which may be for a metal ion-conducting electrochemical device, comprises a metal member; and a metal conducting coating, which may be an epitaxial (e.g., a homoepitaxial) metal conducing coating, disposed on at least a portion of the metal member (e.g., all portions of the metal member that would be or are in contact with the electrolyte of the metal ion-conducting electrochemical device). A metal conducting coating or an anode may be formed by electrodeposition in the presence of a field.

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: Solid-polymer electrolytes, methods of making solid-polymer electrolytes, and uses of solid-polymer electrolytes. A solid-polymer electrolyte comprises a cross-linked polymer network. A cross-linked polymer network may comprise a plurality of groups, which may be cross-linked groups, such as, for example, cross-linked difunctional polyether groups, cross-linked difunctional ionic groups, non-crosslinked groups, which may be referred to as “dangling” groups, or a combination thereof, and a plurality of cross-linked multifunctional crosslinker groups. A solid polymer electrolyte can be formed by polymerization. A solid polymer electrolyte can be formed in situ in a device. A solid polymer electrolyte can be used in devices such as, for example, batteries, supercapacitors, fuel cells, and the like.
