      abstract     = {Lithium ion conductors based on complex oxide materials are
                      considered to be outstanding from their high safety and
                      reasonable Li-ion conductivity. Compared to others solid Li
                      ionic conductors, oxide materials have additional advantages
                      of easier material handling during synthesis, higher
                      chemical stability and wider electrochemical stability
                      window. The high stiffness and electrochemically stability
                      against metallic Li also make oxide-type Li-ion conductors
                      as a perfect Li anode protector when using in Li-S or Li-air
                      batteries. The use of Tantalum-substituted Li7-xLa3Zr2O12
                      (LLZ:Ta) as solid electrolyte for solid-state battery has
                      been reported in several papers. The reported solid-state
                      batteries were all constructed with a thin film cathode
                      which was made either by physical vapor or sol-gel
                      deposition [1-2]. In order to realize a Li-ion battery based
                      on an oxide conductor as solid electrolyte, LLZ:Ta powder
                      was synthesized via different synthesis routes including
                      solid-state reaction. LLZ:Ta pellets with optimized
                      sintering parameters exhibit a high Li-ion conductivity of
                      7.8 x 10-4 S cm-1 at 30 oC with a relative density of
                      $~94\%.$ The material was further implanted as a solid
                      electrolyte by using screen printing to put on thick LiCoO2
                      (> 50 micrometers) as cathode and subsequently tested versus
                      Li metal.Thin-film solid-state batteries allow – on the
                      one hand – a detailed analysis of the compatibility of
                      active storage material and the electrolyte because of
                      well-defined interfaces. On the other hand, thin-film oxide
                      electrolytes might also have the potential for application
                      as thin Li-ion conductive solid-sate separators on porous
                      substrates in Li-S- batteries.[1] M. Kotobuki et al,
