Abstract: A product, according to one general aspect, includes solid state electrolyte particles, each particle individually having a coating thereon, the coating comprising a first metal oxide in a first layer and a second metal oxide in a second layer. The first and second metal oxides are different. A method, according to one general aspect, includes fabricating a product using a powder of solid state electrolyte particles, each particle being coated with a coating formed via 15 cycles or less of atomic layer deposition, the coating comprising a first metal oxide in a first layer and a second metal oxide in a second layer. The first and second metal oxides are different.

Abstract: A product includes a solid state electrolyte particle coated with a coating consisting essentially of metal oxide. A method includes depositing a coating on a solid state electrolyte particle by atomic layer deposition. A method includes fabricating a product using a plurality of solid state electrolyte particles coated with a coating consisting essentially of metal oxide.
