Abstract:Driven by the strong adsorptive and catalytic ability of metal sulfides for soluble polysulfides, it is considered as a potential mediator to resolve the problems of shuttle effect and slow reaction kinetics of polysulfides in lithium−sulfur (Li−S) batteries. However, their further development is limited by poor electrical conductivity and bad long-term durability. Herein, one type of new catalyst composed of SnS/SnS 2 heterostructures on hierarchical porous carbon (denoted as SnS/SnS 2 −HPC) by a simple hydro… Show more
