초록

Li$_2$O-P$_2$O$_{5}$-Bi$_2$O$_3$-V$_2$O$_{5}$ glass containing glass former, P$_2$O$_{5}$ and Bi$_2$O$_3$ was prepard by melting the glass batch in pt. erucible followed by quenching on the copper plate. We found that Li$_2$O-P$_2$O$_{5}$-Bi$_2$O$_3$-V$_2$O$_{5}$ g1ass-ceramics obtained from the crystallization of glass showed significantly higher capacity and longer cycle life tham LiV$_3$O$_{8}$ made from powder synthesis. In this paper, we described crystallization process and LiV$_3$O$_{8}$ crystal growth in glass matrix by increasing temperature. The electrochemical properties were strongly affected by LiV$_3$O$_{8}$ crystal growth in matrix.rowth in matrix.
