Abstract Transition metal sulfides, as an important class of inorganics, can be used excellent electrode materials for various types electrochemical energy storage, such lithium‐ion batteries, sodium‐ion supercapacitors, and others. Recent works have identified that mixing graphene or derivatives with transition sulfides result in novel composites better performance. This review summarizes the latest advances sulfide derivatives. The synthetic strategies morphologies these are introduced....
This paper presents a novel method and rationale for utilizing carbonized MOFs sulphur loading to fabricate cathode structures lithium–sulphur batteries. Unique carbon materials with differing hierarchical pore were synthesized from four types of zinc-containing metal–organic frameworks (MOFs). It is found that made MOFs-derived carbons higher mesopore (2–50 nm) volumes exhibit increased initial discharge capacities, whereas micropore (<2 lead better cycle stability.
