Abstract
Alternative sputter target compositions or configurations for thin-film electrolytes are proposed whereby the sputter target materials system possesses sufficient electrical conductivity to allow the use of (pulsed) DC target power for sputter deposition. The electrolyte film materials adopt their required electrically insulating and lithium-ion conductive properties after reactive sputter deposition from the electrically conducting sputter target materials system.
