초록

Instead of a solution technigue producing amorphous LiV$_3$O$_{8}$ form, we prepared Lithium vanadate glass by melting Li$_2$O-P$_2$O$_{5}$-V$_2$O$_{5}$, composition in pt. crucible and by quenching on the copper plate. From the crystallization of Li$_2$O-P$_2$O$_{5}$-V$_2$O$_{5}$, we could abtain crystal phase, LiV$_3$O$_{8}$. The material heat-treated at lower-temperature, 25$0^{\circ}C$ was less crystalline, but had higher capacity. In present paper, we describe eletrochemical properties during crystallization process and find the best crystallization condition of Li$_2$O-P$_2$O$_{5}$-V$_2$O$_{5}$ glass as cathod material.cathod material.
