| 520 | _ | _ | |a To avoid problems connected to organic liquid electrolytes used in conventional Li-ion batteries, solid electrolytes like lithium conducting sulfides [1], oxides [2] and phosphates [3] can be used in all-solid-state Li-ion batteries. One promising oxide material is the garnet-structured Li7La3Zr2O12 (LLZ) with a reasonable Li-ion conductivity of about 10-4 S/cm, a high thermal (up to 1250°C), chemical (e.g. against metallic lithium) and electrochemical stability (up to 8V vs. Li/Li+). Partially substitution of Li by Al or Zr by Ta lowers the cubic phase crystallization temperature resulting in an increased Li-ion conductivity. In order to compensate the lower Li-ion conductivity compared to liquid electrolytes, the overall internal resistance of the cell can be reduced by applying a thin electrolyte layer. Different approaches have been used to deposit garnet-structured Li7La3Zr2O12 thin films [4, 5] but were not successful yet due to problems with the crystallization of LLZ precursors into garnet structure on non-single-crystal substrate. Deposition of cubic phase Li7La3Zr2O12 layer by r.f. magnetron sputtering was carried out directly on a cathode material coated titanium substrate. Gracing incidence x-ray diffraction reveals the cubic garnet structured phase, LLZ was formed as a thin film electrolyte for a thin film battery. SIMS analysis for internal elemental diffusions between deposited layers, SEM for microstructures, electrochemical tests of the formed LLZ layer and battery are presented as well. |
