Electrospun Polymer Nanofibers with TiO@NiCo-LDH as Efficient Polysulfide Barriers for Wide-Temperature-Range Li-S Batteries.

Herein, we introduce polymer nanofibers of TiO@NiCo-LDH as interlayers into Li-S batteries. From 0 to 60 °C, the interlayers can deliver high sulfur utilization, an outstanding rate capability, and excellent cycling life. High-temperature excitation makes it easier for the valence band electrons of TiO to transition to the conduction band.
