| 520 | _ | _ | |a All solid-state Li batteries based on oxide-class solid electrolyte are considered to be out-standing from the other electrolytes due to their high safety and higher energy density. Among the Li-ion conductive oxides, materials with garnet structure such as Ta-substituted Li7La3Zr2O12 (LLZ:Ta) have been attracting most of attention due to their high total Li-ion conductivity, wide electrochemical stability window, stability against metallic Li and easy handling for fabrication (i.e. inertness to oxygen). The use of LLZ as solid electrolyte for solid-state battery had been reported in several papers. However, the reported solid-state batteries were all constructed with a thin film cathode which was made either by physical vapor or sol-gel deposition. The thin film cathodes were usually under or around 1 m in thickness which made the energy density of these SSBs useful for small scale applications.Electrolyte supported solid-state batteries using LLZ:Ta with thick cathodes (> 50 m) have been constructed in our laboratory by screen-printing process. A proper sintering process was invested for well bonding the thick cathode layer to the supporting electrolyte. The constructed solid-state Li batteries exhibited good charge-discharge utilization of active material of more than 80% which is equal to a capacity density of more than 1 mAh cm-2 at 100 oC. It also exhibited good cycle ability so that one hundred of cycles were achieved. However, the reduction of high internal resistance of the cell is still the major challenge for further improvement of the battery performance, especially if the application of this all solid state Li battery is toward room temperature. During this presentation, results from material chemical stability, cell morphology, electrochemical performance and the challenges of building up Li battery by using LLZ:Ta will be discussed. |
