The 70Li2S·(30 − x)P2S5·xP2S3 (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 × 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.
