Electrode materials systems for planar solid oxide fuel cells with high electrochemical performance including anode materials that provide exceptional long-term durability when used in reducing gases and cathode materials that provide exceptional long-term durability when used in oxygen-containing gases. The anode materials may comprise a cermet in which the metal component is a cobalt-nickel alloy. These anode materials provide exceptional long-term durability when used in reducing gases, e.g., in SOFCs with sulfur contaminated fuels. The cermet also may comprise a mixed-conducting ceria-based electrolyte material. The anode may have a bi-layer structure. A cerium oxide-based interfacial layer with mixed electronic and ionic conduction may be provided at the electrolyte/anode interface.

A method of forming boron nitride nanoparticles. A plurality of precursor molecules comprising boron, nitrogen and hydrogen may be decomposed in a first heating zone to form a plurality of gaseous molecules that contain bonded boron and nitrogen, followed by heating to a second, higher temperature thereby causing the gaseous molecules to react and nucleate to form a plurality of boron nitride nanoparticles. Depending on processing temperatures, the boron nitride nanoparticles may include amorphous forms, crystalline forms, or combinations thereof. Precursor molecules may include ammonia borane, borazine, cycloborazanes, polyaminoborane, polyiminoborane, and mixtures thereof. The boron nitride nanoparticles may be incorporated into a variety of dispersions, composites, and coatings; and in one embodiment, may be a component of a propellant, wherein the boron nitride nanoparticles may confer a range of advantages to gun barrels in which such propellants may be fired.

The instant invention includes a spherical porous secondary silicon-based particle and methods for producing the same. The spherical porous secondary silicon-based particle is comprised of agglomerated primary silicon-based nanoparticles. The secondary particle comprises a carbon coating that reduces the effective exposed surface area of the primary particles to the electrolyte, thus improving first cycle efficiency. The secondary particle further comprises porous regions that enable the silicon nanoparticles to expand during lithiation. Advantages include ease of castability with micron-sized spherical particles, ease of mixing spherical particles, ease of flow for spherical particles in various processing steps, and ease with obtaining higher loading, which translates to higher areal capacity and overall energy density of the cell. A readily scalable process for producing the particles using low-cost materials and low-cost processing methods is disclosed.
