      abstract     = {All-solid-state sodium batteries (ASSNBs), which combine
                      the benefits of high safety and low cost, are expectedto be
                      an alternative or complementary storage technology to
                      lithium ion batteries. Herein, we developed anaqueous tape
                      casting technique for the continuous fabrication of ceramic
                      sheets made of silicate-based Na5YSi4O12(NYS) Na+ ion
                      superionic conductor for the first time. After sintering,
                      the ceramics showed a total conductivityof 1.0 mS cm􀀀 1
                      at room-temperature, low total activation energy of 0.30 eV,
                      and wide electrochemicalwindow of over 8 V. The critical
                      current density of NYS tape against Na-metal electrodes can
                      reach 2.2 mA cm􀀀 2and the galvanostatic cycling time is
                      over 280 h under 0.8 mA cm􀀀 2 and 0.8 mAh cm􀀀 2. The
                      obtained tape hashigh crystalline purity, dense
                      microstructure, favorable mechanical properties (hardness H
                      of 2 GPa and elasticmodulus E of 45 GPa). This work not only
                      highlights the potential of the scarcely studied
                      silicate-based NYS ionicconductor as a functional separator,
                      but also presents a cost-efficient and eco-friendly
                      continuous fabricationusing the aqueous tape casting
                      technique, thus being expected to boost the practical
                      application of NYS as solidstateelectrolyte in ASSNBs.},
