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: Provided herein are solvents for an electrolyte of a battery comprising fluorinated compounds of the present disclosure, batteries comprising: an anode structure including an anode current collector; a cathode structure including a cathode current collector and a cathode material disposed on the cathode current collector; and the electrolyte of the disclosure. Also provided herein are layers of a battery, comprising a fluorinated polymer compounds of the present disclosure.

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.

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: Rechargeable metal batteries are disclosed having a protective ionic membrane layer on a metal anode. The ionic membrane can be formed from ionomers in the electrolyte including polymerizable ionic liquid monomers or halogenated alkyl anion salts. Such ionic membranes can continuously supply ions near the anode electrode and stabilize the anode metal electrode.

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 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.
