      abstract     = {Solid-state lithium batteries (SSLBs) are considered to be
                      one of the most promising nextgeneration Li batteries due to
                      their high capacity and intrinsic safety. Their sustainable
                      processing offers additional advantages over conventional
                      batteries in terms of ecological and economicbenefits.
                      However, the sustainable processing of SSLBs has been only
                      sporadically investigated and need to be optimized.
                      Garnet-type Li7La3Zr2O12 (LLZO) is one representative of
                      oxide-based solid electrolytes (SE) for SSLBs. A thin
                      freestanding LLZO sheet can be fabricated by tape-casting
                      and used e.g. as separator in SSLBs, since tape-casting is
                      an industrially established process and enables large-scale
                      production of such SEs. However, organic solvents and
                      additives employed in conventional slurry recipes for
                      tape-casting give rise to health and safety concerns and
                      additionally cause high cost for solvent recovery. Hence,
                      development of a water-based processing route reduces both
                      manufacturing costs and environmental footprint. In this
                      work, a tape-casting process for LLZO SEs is developed using
                      water as solvent, the watersolublebiopolymer as binder and
                      other harmless polymers as plasticizers. During the aqueous
                      processing, a Li+/H+ exchange takes place, but this Li+/H+
                      exchange reaction is reversible in the procedure and results
                      in the formation of stoichiometric cubic LLZO at the end.
                      The obtained freestanding LLZO thin sheets have a relative
                      density of $90\%$ to the theoretical density and exhibit an
                      ionic conductivity of 0.15 mS cm-1 at room temperature.},
