Abstract:

Lithium-sulfur batteries are considered to be the next-generation secondary batteries with development potentials due to high theoretical specific capacity and low cost. However, there are several limitations of the sulfur cathodes due to the insulating nature of sulfur and Li2S, the “shuttle effect” caused by the intermediate lithium polysulfides(Li2Sx, 4≤x≤8) dissolved and migrated in the electrolyte and serious side effects, resulting in low utilization of the active materials, poor cycling stability and rate performances. In this paper, the research progress of transition metal nano materials in lithium-sulfur batteries is reviewed. Especially, the synthetic methods of materials and the reaction mechanism for inhibiting the dissolution of lithium polysulfide and promoting the conversion are introduced and the development of cathode carrier materials for lithium-sulfur batteries is forecasted.
