摘要：

The 70Li(2)S center dot(30 - x)P2S5 center dot xP(2)S(3) (mol%) glass and glass-ceramic electrolytes were prepared via mechanochemical route using a planetary ball mill apparatus. Ball-milling condition and glass composition for achieving high Li+ ion conductivity in glass-ceramic electrolytes were investigated. The glass-ceramics prepared using ZrO2 media (500 balls, 4 mm in diameter) exhibited higher conductivity than those prepared using Al2O3 media (10 balls, 10 mm in diameter). The former experiment condition was appropriate for preparing homogeneous glasses. The substitution of 1 mol% of P2S3 for P2S5 enhanced the conductivity of the glass-ceramics and the maximum conductivity was 5.4 x 10(-3) S cm(-1) at room temperature. The Li7P3S11 analogous phase, Li7P3S11 (-) (z), was formed at the composition with 1 mol% P2S3 and the Li7P3S11 (- z) phase would have higher conductivity than the Li7P3S11 crystal without substitution.
