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.

Conducting coatings for anodes, methods of making and using same, and uses thereof

Provided are compositions including one or more cyclic ether(s), one or more salt(s), which may be one or more lithium salt(s), one or more sodium salt(s), or a combination thereof, and, optionally, one or more ring-opening polymerization initiator(s). The compositions may be used to form solid-state electrolytes. Also provided are methods for forming solid-state electrolytes using the compositions and devices comprising one or more composition(s) or one or more solid-state electrolyte(s) using the compositions.

In situ formation of solid-state polymer electrolytes for batteries

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.

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.

Organized materials on a substrate. The organized materials are monolayer(s) of close-packed nanoparticles and/or microparticles. The organized materials can be formed by transfer of one or more monolayers to a substrate from a coating composition on which a monolayer of close-packed nanoparticles and/or microparticles is formed. Organized materials on a substrate can be used in devices such as, for example, batteries, capacitors, and wearable electronics.

A metal-based battery includes at least one metal electrode immersed within an electrolyte that includes: (1) an aprotic solvent; (2) a simple halogen containing material; and (3) optionally a metal salt that includes a complex halogen containing anion. The simple halogen containing material may include a metal halide salt that includes a metal cation selected from the group including but not limited to lithium and sodium metal cations. The metal halide salt may also include a halide anion selected from the group consisting of fluoride, chloride, bromide and iodide halide anions.

Sulfur containing nanoparticles that may be used within cathode electrodes within lithium ion batteries include in a first instance porous carbon shape materials (i.e., either nanoparticle shapes or 'bulk' shapes that are subsequently ground to nanoparticle shapes) that are infused with a sulfur material. A synthetic route to these carbon and sulfur containing nanoparticles may use a template nanoparticle to form a hollow carbon shape shell, and subsequent dissolution of the template nanoparticle prior to infusion of the hollow carbon shape shell with a sulfur material. Sulfur infusion into other porous carbon shapes that are not hollow is also contemplated. A second type of sulfur containing nanoparticle includes a metal oxide material core upon which is located a shell layer that includes a vulcanized polymultiene polymer material and ion conducting polymer material. The foregoing sulfur containing nanoparticle materials provide the electrodes and lithium ion batteries with enhanced performance.

A non-aqueous Na-oxygen battery utilizes a gas mixture of COand Oas fuel. The battery exhibits a comparatively high specific energy of 6500-7000 Whkgover a range of COfeed compositions. The energy density achieved is higher, by 200% to 300%, than obtained with pure oxygen feed. Ex-situ FTIR and XRD analysis confirm Na2O2, NaCOand NaCOas discharge products. The Na&#x2014;O/CObattery provides a promising approach for COcapture and conversion into electrical energy. The Na&#x2014;O/CObattery may be extended to other metals. In addition, operation of a metal battery fueled at least in-part by carbon dioxide within an optimal temperature range is considered.
