摘要:

本文通过实验和计算相结合的方法,研究了Na_3SbS_4的相变,并合成了难高温保存的立方相Na_3SbS_4(c-Na_3SbS_4)。通过Rietveld精修和电化学阻抗谱证实了c-Na 3SbS 4的形成。实验和理论计算均表明,c-Na_3SbS_4的离子电导率高于t-Na_3SbS_4,但二者的数值在同一数量级。这两种结构都允许快速离子传输。

英文摘要:

In this work, a comprehensive research coupling experiment and computation has been performed to understand the phase transition of Na3SbS4 and to synthesize cubic Na3SbS4 (c-Na3SbS4), a high temperature phase of Na3SbS4 that is difficult to be preserved from high temperature. The formation of c-Na3SbS4 is verified by Rietveld refinement and electrochemical impedance spectroscopy. Both experiment and theoretical calculation reveal that the ionic conductivity of c-Na3SbS4 is higher than that of t-Na3SbS4, though the values are in the same order of magnitude. Both structures allow fast ion transport.
