Abstract
Official abstract text for this publication.
An intermediary solid electrolyte structure having a Li ion conducting solid electrolyte layer covered with a thin as-deposited lithium phosphorus nitride film. A surface protected solid electrolyte having a solid electrolyte layer having a first major surface that is covered by a composite protective film, the composite protective film having a lithium phosphorus material component and a phosphorus nitride material component. A physical vapor deposition target for the deposition of a composite protective film, the target having a compacted composite material target having a mosaic structure. Methods of making thin films.
First claim
Opening claim text (preview).
What is claimed: 1 . A physical vapor deposition target for the deposition of a composite protective film, the target comprising a backing plate and a compacted composite material target on the surface of the backing plate, the composite material target having a mosaic structure and comprising a first and second material component, wherein the first material component is a lithium phosphate material, and the second material component is a phosphorus nitride material wherein the first material component is in the form of a substantially dense layer and the second material component is in the form of a pressed pellets distributed onto the surface of the lithium phosphate dense layer. 2 . The physical vapor deposition target of claim 1 wherein a significant percentage of the surface of the dense lithium phosphate layer is covered by pellets of the phosphorus nitride second material, wherein the surface coverage is at least 10%. 3 . The physical vapor deposition target of claim 1 wherein a significant percentage of the surface of the dense lithium phosphate layer is covered by pellets of the phosphorus nitride second material, wherein the surface coverage is at least 50%. 4 . The physical vapor deposition target of claim 3 wherein the lithium phosphate material is Li 3 PO 4 or LiPO 3 .
