Researchers from Peking University and Beijing Institue of Technology have designed a Li-sulfur battery cathode based on sulfur and a metal-organic framework (MOF) host. In a paper in the RSC journal Energy & Environmental Science, the team reports high discharge capacities and long cycle life.

Unlike an intercalation cathode which has an intrinsic host structure made of redox metal sites allowing the transport of Li+/e-, sulfur as a conversion cathode requires an additional host to store and immobilize the mobile redox centers, polysulfides. Metal-organic frameworks as a class are highly porous and well-defined crystalline materials, and a good prospect for such a host, the researchers posited.
