The practical application of lithium/sulfur (Li/S) batteries is hindered by the migration of soluble polysulfides (Li<sub>2</sub>S<sub>n</sub>, 4 ≤ n ≤ 8) from cathode to anode, leading to poor electrochemical stability of the cell. To address this issue, in the present study, a TiO<sub>2</sub>/porous carbon (TiO<sub>2</sub>/PC) composite-coated Celgard 2400 separator was successfully fabricated and used as a polysulfide barrier for the Li/S battery. In TiO<sub>2</sub>/PC, the highly conductive ...[more]
