A KAIST research team has developed ultra-stable, high-rate lithium-sulfur batteries (LSBs) by using hierarchically porous titanium nitride (h-TiN) as a sulfur host. In a paper in the journal Advanced Materials , the researchers report that h-TiN/S shows a reversible capacity of 557 mAh g ?1 even after 1000 cycles at 5 C rate with only 0.016% of capacity decay per cycle.
