A paper featured on the inside back cover of February 2021 edition of Advanced Energy Materials proposes a novel cathode structure, where iron atomically dispersed in a carbon nitride material (Fe/C2N) acts as an effective sulfur host, improving the efficiency and stability of lithium-sulfur batteries.
This work was led by ICREA Prof. Andreu Cabot, leader of the Functional Nanomaterials group at IREC and ICREA Prof. Jordi Arbiol, from ICN2.
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 the shuttle effect of lithium polysulfides (LiPS). In the Advanced Energy Materials paper, a 2D layered organic material, C2N, loaded with atomically dispersed iron as an effective sulfur host in LSBs is reported. The work provides a rational structural design strategy for the development of high‐performance cathodes based on atomically dispersed catalysts for LSBs.
