AB In this work, we propose a processing methodology, based on the combination of tape-casting and low temperature hot-pressing, to develop ceramic NASICON electrolytes with formula Na3.16Zr1.84Y0.16Si2PO12 towards the attainment of solid-state sodium batteries operating at room temperature. Solid-state NASICON electrolytes with very good mechanical properties and high ionic conductivity are successfully tested in terms of electrochemical behavior by using the cell configuration: Na/NASICON/FePO4. Following charge-discharge cycles, an unusual redox pair of FePO4 is found, indicating that the all-solid-state battery with the Na metal anode may be effectively operated at room temperature. At a charge/discharge current density of C/20, the solid-state battery has an initial reversible discharge capacity of 85 mAh/g. Because of its relatively high ionic conductivity and thermostability, when in contact with the Na anode and the FePO4 cathode, the NASICON ceramic electrolyte is a viable option for attaining reliable, safer and sustainable all-solid-state batteries operating at room temperature.
