【 摘 要 】

Surface of TiO$_2$ is known to chemically bind the polysulfides in Li–S cell. In the present study, the effect of surface defects or oxygen vacancies in TiO$_2$present as a composite with sulfur cathode on the performance of Li–S cell wasinvestigated by using NaBH$_4$ reduced (black colour) TiO$_2$ and pristine (white) TiO$_2$ in cathode. Results show that former is superior in performance.
