Abstract

Composite electrodes composed of amorphous titanium polysulfide (a-TiS x) and titanium disulfide (TiS2) were designed for application in all-solid-state batteries. The conductivity of the a-TiS x/TiS2-based working electrode was higher than that of the amorphous TiS4 (a-TiS4); the reversible capacity of the cell using a-TiSx/TiS2 electrode was higher than that of the cell using a-TiS4. Designing nanocomposite materials such as the a-TiSx/TiS2 described in this paper is an effective way to improve the performance of all-solid-state batteries.
