Abstract:
An article having a metallic layer and a glass layer, and a method for preventing or reducing a chemical reaction between a metallic layer and a glass layer are disclosed. The article has a barrier layer disposed between the metallic layer and the glass layer. The barrier layer includes alumina and a phosphate. The phosphate includes an aluminum dihydrogen phosphate, an aluminum-containing phosphate, a phosphate of an element of the metallic layer, a phosphate of an element of the glass layer, or combinations thereof. The method includes disposing a barrier layer between the metallic layer and the glass layer.
Abstract:
A method for preparing an electrolyte separator for an electrochemical device is described. The method includes the step of applying a beta″-alumina coating composition, or a precursor thereof, to a porous substrate, by an atmospheric, thermal spray technique. An electrochemical device is also described. Some of these devices include an anode, a cathode, and an electrolyte separator disposed between the anode and the cathode. The separator includes a thermally-sprayed layer of beta″-alumina, disposed on a porous substrate. The electrochemical device can be used as an energy storage system, or for other types of end uses.
