Bram.Institute of Energy and Climate Research (IEK-1), Forschungszentrum Jülich GmbH, D-52425 JülichAll solid state lithium ion batteries (ASB) are, in comparison to conventional Lithium ion batteries (LIB) which using organic liquids, much safer due to their non-flammable property. Oxide ceramic lithium ion conductors such as Li7La3Zr2O12 (LLZ) [1] have the advantage of inertness against oxygen, stability against lithium metal, wide electrochemical window (8V vs. Li/Li+), which makes it as one of the most promising candidates for all solid state battery application. It had been reported that garnet structured LLZ has a tetragonal and cubic phase, for which cubic generally exhibit higher Li+ ion conductivity (σ ≈ 10-4 S cm-1) [2]. The substitution of Al [2], Ta [3] and Y [4] to different sites in the LLZ structure can be used to stabilize the material in its cubic phase at room temperature.  However, to bridge between lab works and real application, large size LLZ functional layers need to be fabricated by different established technologies.  The investigated materials have therefore been used for slurry development, processing by tape casting and sintering studies in order to obtain highly dense films.
