摘要：

Lithium-ion conducting glass-ceramic electrolyte in the composition 75Li(2)S center dot 5P(2)S(3) center dot 20P(2)S(5) (mol%) was prepared by heat treatment of an amorphous precursor. The amorphous precursor was obtained by a high-energy ball-milling process. The glass ceramic showed high ion conductivity 2.0 x 10(-3) S cm(-1) at room temperature. Raman scattering measurements suggested that the glass ceramic essentially composed of thio-phosphate anions, PS43- and P2S64-, as structural units. A laboratory-scale all-solid-state battery was also assembled by use of the glass ceramic as solid electrolytes and LiNi1/3Mn1/3Co1/3O2 powders as positive electrode materials. The all-solid-state battery showed good charge-discharge cycle performance at room temperature under a constant current density of 0.1 mAcm(-2). (C) 2013 Elsevier B.V. All rights reserved.
