Abstract
Amorphous based solid electrolytes are promising for application to solid-s tate batteries and other electrochemical devices. We have prepared a number of the electrolytes by rapid quenching of melts using a twin-roller and by mechanical milling of starting materials using a planetary ball mill. Thre e topics of silver or lithium ion conducting amorphous electrolytes prepare d by these techniques are reported. The first one is the formation and char acterization of alpha -AgI microcrystal-dispersed composite electrolytes, i n which high temperature superionic phase of alpha -AgI is stabilized at ro om temperature in a superionic glass matrix. The second one is the structur al investigation of lithium ion conducting oxysulfide glasses prepared by r apid quenching of melts. The last one is the mechanochemical. preparation o f high lithium ion conducting oxysulfide glasses and their application to s olid-state secondary batteries.
