Abstract
- The practical application of lithium‐sulfur (Li−S) batteries is greatly hindered by the shuttle effect of dissolved polysulfides in the sulfur cathode and the severe dendritic growth in the lithium anode. Adopting one type of effective host with dual‐functions including both inhibiting polysulfide dissolution and regulating Li plating/stripping, is recently an emerging research highlight in Li−S battery. This review focuses on such dual‐functional hosts and systematically summarizes the recent research progress and application scenarios. Firstly, this review briefly describes the stubborn issues in Li−S battery operations and the sophisticated counter measurements over the challenges by dual‐functional behaviors. Then, the latest advances on dual‐functional hosts for both cathode and anode in Li−S full cells are catalogued as species, including metal chalcogenides, metal carbides, metal nitrides, heterostuctures, and the possible mechanisms during the process. Besides, we also outlined the theoretical calculation tools for the dual‐functional host based on the first principles. Finally, several sound perspectives are also rationally proposed for fundamental research and practical development as guidelines. [ABSTRACT FROM AUTHOR]
