摘要：

Lithium ion conducting oxysulfide glasses were prepared in the systems (0.6Li(2)S . 0.4SiS(2))-Li(x)MO(y) (Li(x)MO(y) = Li3BO3, Li4SiO4, Li3PO4, Li4GeO4) by twin-roller rapid quenching. In any case of Li(x)MO(y) the addition of 5 mol% Li(x)MO(y) improved the ionic conductivity and the stability against crystallization. At the same composition a large number of silicon atoms in the grasses were coordinated with both sulfur and oxygen atoms. Such unique structural units contributed to improve the conductivity and the stability against crystallization.
