Abstract

<p>Solid state lithium battery, Li4/3+xTi5/3O4/Li1−xCoO2, was constructed by using a Li+ ion conductive sulfide glass as an electrolyte. The coin type battery with dimensions of 12mm in diameter and l.6mm in thickness had a discharge capacity of 2.8mAh. The battery showed an excellent cycling ability. There was no degradation in coulombic efficiency even in the case of continuous charging. It suggests that side reaction is negligible due to the electrochemical stability of the solid electrolyte.</p>
