A High-performance Electrolyte for Monolithic Solid-State Sodium Battery with Al3+ Doped Na3Zr2Si2PO12
All solid-state sodium batteries (SSSB) are superior in energy density and safety over sodium ion batteries. Due to the employment of solid-state electrolytes (SSE) and sodium metal anodes, short circuits caused by sodium dendrites may be avoided. Na3Zr2Si2PO12 (NZSP)-type materials meet most of the requirements as promising SSEs. The Na conductivity may be enhanced by suitable elemental doping, achieving sufficient ionic conductivity ( >10-3 S cm-1) to satisfy the requirements of SSSBs. We designed novel Na3+2xZr2-xAlxSi2.4P0.6O12 (Al-NZSP, x = 0, 0.1, 0.25) electrolytes where the total conductivity was increased to 4.0×10-3 S/cm. We propose a structural study to discriminate changes in the oxygen coordination and thermal displacement factors of mobile Na+ ions upon Al doping in NZSP. Additionally, this NASICON-like structural type undergoes a structural transition in the 200-300ēC range, from monoclinic to rhombohedral, involving an additional reduction of the activation energy for Na motion. Thus we aim to study the crystal structure evolution across the phase transition, to correlate the changes in the framework with the transport properties.
