Abstract

Described is a core-shell nanoparticle comprising a lithium sulfide nanoparticle core and a shell covering the lithium sulfide nanoparticle core, the shell comprising at least one of carbon, polyanaline or a transition metal sulfide. The core-shell nanoparticle may be used for a positive electrode in a lithium/sulfur battery cell.

Process to make core-shell structured nanoparticles

Patent Luhrs, Claudia; Phillips, Jonathan; Richard, Monique N

Disclosed is a process for making a composite material that contains core-shell structured nanoparticles. The process includes providing a precursor in the form of a powder a liquid and/or a vapor of a liquid that contains a core material and a shell material, and suspending the precursor in an aerosol gas to produce an aerosol containing the precursor. In addition, the process includes providing a plasma that has a hot zone and passing the aerosol through the hot zone of the plasma. As the aerosol passes through the hot zone of the plasma, at least part of the core materialmore »« less

Patent Stamenkovic, Vojislav; Markovic, Nenad; Kang, Yijin

A multimetallic core/interlayer/shell nanoparticle comprises an inner core formed from a first metal. An interlayer is disposed on the first layer. The interlayer includes a plurality of gold atoms. An outer shell is disposed over the interlayer. The outer shell includes platinum and the first metal. A surface of the NP is substantially free of gold. The first metal is selected from the group consisting of nickel, titanium, chromium, manganese, iron, cobalt, copper, vanadium, yttrium, ruthenium, palladium, scandium, tin, lead and zinc.

Nitride stabilized core/shell nanoparticles

Patent Kuttiyiel, Kurian Abraham; Sasaki, Kotaro; Adzic, Radoslav R.

Nitride stabilized metal nanoparticles and methods for their manufacture are disclosed. In one embodiment the metal nanoparticles have a continuous and nonporous noble metal shell with a nitride-stabilized non-noble metal core. The nitride-stabilized core provides a stabilizing effect under high oxidizing conditions suppressing the noble metal dissolution during potential cycling. The nitride stabilized nanoparticles may be fabricated by a process in which a core is coated with a shell layer that encapsulates the entire core. Introduction of nitrogen into the core by annealing produces metal nitride(s) that are less susceptible to dissolution during potential cycling under high oxidizing conditions.
