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.
