Atomically dispersed Fe in a C2N based catalyst as a sulfur host for efficient lithium-sulfur batteries

Lithium-sulfur batteries (LSBs) are considered to be one of the most promising next generation energy storage systems due to their high energy density and low material cost. However, there are still some challenges for the commercialization of LSBs, such as the sluggish redox reaction kinetics and t...

However, there are still some challenges for the commercialization of LSBs, such as the sluggish redox reaction kinetics and the shuttle effect of lithium polysulfides (LiPS).

Even at a high sulfur loading of 3 mg cm, they deliver remarkable specific capacity retention of 587 mAh g after 500 cycles at 1 C.
