    摘要： Forming a lithium lanthanum zirconate thin film includes disposing zirconium oxide on a substrate to yield a zirconium oxide coating, contacting the zirconium oxide coating with a solution including a lithium salt and a lanthanum salt, heating the substrate to yield a dried salt coating on the zirconium oxide coating, melting the dried salt coating to yield a molten salt mixture, reacting the molten salt mixture with the zirconium oxide coating to yield lithium lanthanum zirconate, and cooling the lithium lanthanum zirconate to yield a lithium lanthanum zirconate coating on the substrate. In some cases, the zirconium oxide coating is contacted with an aqueous molten salt mixture including a lithium salt and a lanthanum salt, the molten salt mixture is reacted with the zirconium oxide coating to yield lithium lanthanum zirconate, and the lithium lanthanum zirconate is cooled to yield a lithium lanthanum zirconate coating on the substrate.

    摘要： A transition metal hydroxy-anion electrode material for lithium-ion battery cathodes includes the charge-neutral structure Mx(OH)n(XO4)m, where M is one or more transition metals, x is the total number of transition metal atoms, X is sulfur or phosphorus, and x, n, and m are integers. The polyanion material has a nanostructured morphology. (OH)n(XO4)m is a hydroxysulfate or hydroxyphosphate, and M can be one or more (e.g., a solid solution of) transition metals selected from the group consisting of copper, iron, manganese, nickel, vanadium, cobalt, zinc, chromium, and molybdenum. A lithium-ion battery may have a cathode including Mx(OH)n(XO4)m as a cathode material, and an electronic device may include a lithium-ion battery having a cathode including Mx(OH)n(XO4)m as a cathode material.

    摘要： Fabricating a layer including lithium lanthanum zirconate (Li7La3Zr2O12) layer includes forming a slurry including lanthanum zirconate (La2Zr2O7) nanocrystals, a lithium precursor, and a lanthanum precursor in stoichiometric amounts to yield a dispersion including lithium, lanthanum, and zirconium. In some cases, the dispersion includes lithium, lanthanum, and zirconium in a molar ratio of 7:3:2. In certain cases, the slurry includes excess lithium. The slurry is dispensed onto a substrate and dried. The dried slurry is calcined to yield the layer including lithium lanthanum zirconate.

    摘要： Exfoliating transition metal oxide lithium intercalation particles having lithium ions intercalated between transition metal oxide nanosheets includes electrochemically oxidizing a transition metal in first transition metal oxide lithium intercalation particles from a first oxidation state to a second oxidation state, inserting first cations having a radius exceeding the radius of a lithium ion into the vacancies, reducing the transition metal from the second oxidation state to the first oxidation state, and exfoliating the transition metal oxide nanosheets from the second transition metal oxide lithium intercalation particles to yield dispersed transition metal oxide nanosheets comprising the transition metal in the first oxidation state and oxygen. The dispersed transition metal oxide nanosheets can be reassembled to yield a material suitable for a lithium-ion battery cathode. Metal oxide sodium intercalation particles can be similarly exfoliated and reassembled to yield a material suitable for a sodium-ion battery cathode.
