Abstract: Nickel-rich layered oxide electrodes are described herein having high conductivity coatings which, in some embodiments, mitigate degradative pathways, maintain electrode performance and enhance electrode lifetimes. In one aspect, an electrode comprises nickel-rich layered oxide, and a sulfide-based coating or oxide-based coating over the nickel-rich layered oxide, the sulfide-based or oxide-based coating having an ionic conductivity greater than 1×10?4 S/cm at room temperature. In some embodiments, the ionic conductivity is at least 1×10?3 S/cm at room temperature. Moreover, the sulfide-based coating can comprise a ternary sulfide, the ternary sulfide comprising lithium and aluminum.

Abstract: A capacitor is provided for high temperature systems. The capacitor includes: a substrate formed from silicon carbide material; a dielectric stack layer, including a first layer deposited on the substrate and a second layer deposited on the first layer; a Schottky contact layer deposited on the second layer; and an Ohmic contact layer deposited on the substrate. The first layer is formed with aluminum nitride (AlN) epitaxially, and the second layer is formed with aluminum oxide (Al2O3). AlN and Al2O3 are ultrawide band gap materials, and as a result, they can be use as the dielectric in the capacitor, allowing the capacitance changes to be less than 10% between ?250° C. and 600° C., which is very effective for the high temperature systems.

Abstract: 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.
