ABSTRACT:
A solid electrolyte including a composition represented by Formula 1 below is provided: aLi2O-bB2O3-cM-dX (1) wherein M is at least one selected from the group consisting of TiO2, V2O5, WO3, and Ta2O5; X is at least one selected from LiCl and Li2SO4; 0.4<a<0.55; 0.4<b<0.55; 0.02<c<0.05; a+b+c=1, and 0≦d<0.2. A method for preparing the solid electrolyte and a battery using the solid electrolyte are also provided. The solid electrolyte exhibits high ionic conductivity. Lithium and thin film batteries using the solid electrolyte are improved in charge/discharge rate, power output, and cycle life.
