The ever-increasing need for sustainable development requires advanced battery techniques beyond the current generation of lithium ion batteries.Among all candidates being explored,lithium-sulfur batteries are a very promising system to be commercialized in the near future.Towards this end,the development of lithium sulfide (Li2S) nanocrystal-based cathodes has received tremendous effort and witnessed mul-tiple reviews.Differentiated from the focus on performance improvement in previous reviews,this review summarizes the research progress in line with the approaches of materials synthesis and elec-trode fabrication.The key chemistry,operation procedure,materials characterizations and performance assessments are all given a balanced description.Moreover,all approaches are collectively analyzed along the lines of six criteria towards practical applications,i.e.,electrode performance,materials quality,resources sustainability,production cost,operation procedure,and consumed energy.Finally,some per-spective viewpoints on the future research directions are offered.
