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. |
