Lithium–Sulfur Batteries: Approaching Ultrastable High‐Rate Li–S Batteries through Hierarchically Porous Titanium Nitride Synthesized by Multiscale Phase Separation (Adv. Mater. 3/2019)

Abstract

Abstract A noncarbonaceous material (titanium nitride, TiN) with well‐defined multiscale porous architecture is easily developed by multiscale phase separation and applied as a sulfur host for lithium–sulfur batteries, as described by Jinwoo Lee and co‐workers in article number 1806547. The synergistic effect between the unique porous architecture and surface chemical properties of TiN enables ultrastable, high‐rate lithium–sulfur batteries.
