Preparation of Sodium Ion Conductive Na10GeP2S12 Glass-ceramic Electrolytes
Na10GeP2S12 glass and glass-ceramic were synthesized here for the first time via mechanical milling and subsequent heat treatment. The Na10GeP2S12 phase prepared in this study had a similar crystal structure to the Na10SnP2S12 phase reported previously. The ionic conductivity at room temperature and the activation energy of the Na10GeP2S12 glass-ceramic were 1.2 x 10(-5) Scm(-1) and 44 kJ mol(-1), respectively.
