| 英文摘要 | The nanosized Na11Sn2PS12 solid electrolyte with a particle size of around 200 nm is synthesized using the liquid-phase method using 1,2-dimethoxyethane. The sintering conditions for Na11Sn2PS12 crystallization are systematically optimized to maximize ionic conductivity. The highest room temperature ionic conductivity of the liquid-phase-synthesized Na11Sn2PS12 electrolytes (LP-Na11Sn2PS12) is 1.73 x 10(-4) S cm(-1), which is comparable with that of ball-milling samples (BM-Na11Sn2PS12) of 2.16 x 10(-4) S cm(-1). Both Na11Sn2PS12 electrolytes show an electrochemical window of 0.3-3.2 V. Moreover, the as-synthesized Na11Sn2PS12 electrolytes are employed as solid electrolytes in TiS2/Na11Sn2PS12/Na all-solid-state batteries. The TiS2/LP-Na11Sn2PS12/Na battery shows a higher reversible capacity of 142.4 mAh g(-1) compared with 110.5 mAh g(-1) for the TiS2/BM-Na11Sn2PS12/Na battery after 10 cycles under 20 mA g(-1) at 25 degrees C. The better performance of the TiS2/LP-Na11Sn2PS12/Na battery can be ascribed to improved solid-solid contact between the electrolyte and the electrode arising from the nanosized particles of LP-Na11Sn2PS12 electrolytes. |
