Nanoscale SOFC electrode architecture engineered using atomic layer deposition

Title: Nanoscale SOFC electrode architecture engineered using atomic layer deposition

Abstract

One embodiment includes forming surface-modifying phases on a surface of a functional electrode via atomic layer deposition and controlling the chemistry of constituent phases, the crystalline nature of the constituent phases and the thickness of the surface-modifying phase via the atomic layer deposition such that the thickness is between about 2 nm to about 200 nm. The surface-modifying phases enhances the performance of electrocatalytic activity of the functional electrode and the device.

Methods for using atomic layer deposition to produce a film for solid state electrolytes and protective electrode coatings for lithium batteries

Patent Elam, Jeffrey W.; Meng, Xiangbo

A method for using atomic layer deposition to produce a film configured for use in an anode, cathode, or solid state electrolyte of a lithium-ion battery or a lithium-sulfur battery. The method includes repeating a cycle for a predetermined number of times in an inert atmosphere. The cycle includes exposing a substrate to a first precursor, purging the substrate with inert gas, exposing the substrate to a second precursor, and purging the substrate with inert gas. The film is a metal sulfide.

Atomic layer deposition of metal sulfide thin films using non-halogenated precursors

Patent Martinson, Alex B. F.; Elam, Jeffrey W.; Pellin, Michael J.

A method for preparing a metal sulfide thin film using ALD and structures incorporating the metal sulfide thin film. The method includes providing an ALD reactor, a substrate, a first precursor comprising a metal and a second precursor comprising a sulfur compound. The first and the second precursors are reacted in the ALD precursor to form a metal sulfide thin film on the substrate. In a particular embodiment, the metal compound comprises Bis(N,N'-di-sec-butylacetamidinato)dicopper(I) and the sulfur compound comprises hydrogen sulfide (H.sub.2S) to prepare a Cu.sub.2S film. The resulting metal sulfide thin film may be used in among other devices, photovoltaicmore »« less

Nanostructure templating using low temperature atomic layer deposition

Patent Grubbs, Robert K [Albuquerque, NM]; Bogart, Gregory R [Corrales, NM]; Rogers, John A [Champaign, IL]

Methods are described for making nanostructures that are mechanically, chemically and thermally stable at desired elevated temperatures, from nanostructure templates having a stability temperature that is less than the desired elevated temperature. The methods comprise depositing by atomic layer deposition (ALD) structural layers that are stable at the desired elevated temperatures, onto a template employing a graded temperature deposition scheme. At least one structural layer is deposited at an initial temperature that is less than or equal to the stability temperature of the template, and subsequent depositions made at incrementally increased deposition temperatures until the desired elevated temperature stability ismore »« less
