Abstract: Methods of making a textured metal or a textured metal layer, anodes, and devices. In various examples, a method comprises rolling a metal; and folding the rolled metal. In various examples, the rolling and folding are repeated a desired number of times. In various examples, the rolling(s) result(s) in severe plastic deformation (SPD) of the metal, anisotropic deformation(s), or alignment of the metal, or any combination thereof. In various examples, the metal comprises potassium, sodium, lithium, zinc, magnesium, aluminum, calcium, or the like, or any combination thereof. In various examples, an anode comprises a textured metal. In various examples, the textured metal epitaxially templates deposition of the reduced form of metal-ions of a metal ion-conducting electrochemical device. In various examples, a device, such as, for example, a battery (e.g., an ion-conducting battery), a supercapacitor, a fuel cell, an electrolyzer, or an electrolytic cell, comprises one or more of the anode(s).

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: Anodes and anode materials, methods of making anodes and anode materials, and devices. The anode and anode materials comprise an electrically conducting three-dimensional (3-D) matrix, for example, an electrically conducting 3-D carbon matrix or a metal foam, comprising a plurality of chemical bonding groups disposed on a surface of the electrically conducting 3-D matrix or metal foam. The chemical bonding groups can form chemical bond(s) with an electrochemically-deposited electrochemically active metal. The electrochemically-deposited electrochemically active metal can have desirable propert(ies), such as, for example, no observable discontinuities, isolated (orphaned) deposits, or both. An anode or anode material may be formed by functionalizing an electrically conducting 3-D matrix, which may be functionalized. A functionalized electrically conducting 3-D matrix may be formed in a device. A device, such as, for example,. a battery, a supercapacitor, a fuel cell, an electrolyzer, or an electrolytic cell, comprises one or more anode(s) or anode material(s).

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.
