Abstract: Provided is a lithium metal anode comprising a Langmuir-Blodgett films as an artificial solid electrolyte interface layer, a lithium metal battery comprising the same, and a preparation method thereof. Various ultra-thin film layers made of carbon and ceramic are formed on the surface of the LiM to serve as a stable artificial SEI layer and suppress formation and perforation of lithium dendrite and side reactions.

Abstract: 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. The use of the metal halide salt within the metal-based battery provides enhanced cycling ability within the metal-based battery. Also contemplated are additional simple halogen containing material additives that may enhance cycling performance of a metal-based battery.

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.

Abstract: 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.
