In general, the present disclosure is directed to methods for synthesizing vanadium oxide nanobelts, as well as the corresponding chemical composition of the vanadium oxide nanobelts. Also described are materials which can incorporate the vanadium oxide nanobelts, such as including the vanadium oxide nanobelts as a cathode material for use in energy storage applications (e.g., batteries). The vanadium oxide nanobelts described herein display structural characteristics that may provide improved diffusion and/or charge transfer between ions. Thus, batteries incorporating implementations of the current disclosure may demonstrate improved properties such as higher capacity retention over charge discharge cycling.

A low-cost and easy-to-fabricate mixed eand COconducting membrane for advanced high-flux and selective electrochemical COseparation from flue gas is provided. The membrane includes a CO-conducting molten carbonate phase and an e-conducting lithiated Ni-oxide interphase that can be formed in situ during operation. The membrane exhibits a COflux density greater than 0.8 mL/(minute&#xb7;cm) at 850&#xb0; C. with a selectivity ranging from about 100 to about 500 and excellent stability for up to about 450 hours. Further, the self-formed interphase LiNiOis highly electron conducting and can provide electrons to the co-reduction of COand Ointo CO. Such a membrane is an alternative to the conventional 'size-sieving' inorganic and 'dissolution-diffusion' organic counterparts for COcapture from flue gas.

A novel method to produce ALD films disposed on powders is disclosed. Examples include the formation of a cobalt doped zirconia (CDZ), hafnia, and cobalt doped hafnia (CDH) films on lanthanum strontium cobalt iron oxide (LSCF) powder for solid oxide fuel cell cathodes. The coated powders are sintered into porous cathodes that have utility for preventing the migration of cations in the powder to the surface of the sintered cathode and/or other performance enhancing attributes.

The present disclosure relates to a method for synthesis of a porous solid oxide matrix. The method includes synthesizing a composite by co-precipitating a porous ceramic material with a sacrificial material. The composite is sintered and the sacrificial material of the sintered composite is reduced. A porous solid oxide matrix is formed from the reduced and sintered composite. Porosity of the solid oxide matrix is controlled by a volume fraction of the sacrificial material or sintering temperature and a volume fraction of the sacrificial material. Pore size of the solid oxide matrix is controlled by sintering temperature and a volume fraction of the sacrificial material.

The outer surface of a metal electrodeof a rechargeable oxide-ion battery (ROB) cell is covered by its own dense electrolyteand interconnection, where the dense electrolyteand interconnectionhermetically seal the metal electrode away from oxygen-containing environment to prevent direct contact between active metal and oxygen which would lead to self discharge, thus, producing a self-sealed metal electrode of a ROB cell without introducing additional sealing components.
