a Cycling performance with PP, anatase TiO2/PP, GO/PP and Ti0.87O2/PP separators at 0.2 C for 500 cycles. b Long-term cycling stability of a Li-S cell with the Ti0.87O2/PP separator at 1 C for 5000 cycles. c Comparison of surface area mass loading and cycling performance for Ti0.87O2 nanosheets and some other reported functional layers on commercial separators in Li-S cells. Further details of the selected functional materials are provided in the Supplementary Table S1. d Cycling performance of a Li-S cell with the Ti0.87O2/PP separator at a sulfur mass loading of 3.5 mg cm−2. e Cycling performance of a flexible Li-S pouch cell with the Ti0.87O2/PP separator under different bending angles.
