【Abstract】 Solid-state lithium batteries have become the first choice for the next generation of high-safety and high-energy-density battery systems because they do not contain organic electrolytes. Solid electrolyte is one of the core technologies of solid-state battery research. In this paper, with the help of the scientific knowledge map, we used two scientometric tools, CiteSpace and VOSviewer, to conduct co-citation, co-word and cluster analysis of the literature on solid electrolytes for lithium batteries in the Web of Science database from 2012 to the present in the past ten years, revealing research frontiers and hotspots in the field. The results show that there are 5 very active research fronts and 6 hotspots in this current field of research. The research fronts are(1)garnet-type solid electrolyte;(2)stabilized lithium metal anode;(3)polymer composite electrolyte;(4)sulfide superionic conductor and(5)solid electrolyte interface phase. And the 6 hotspots include(1) research on ionic conductivity of garnet-type solid-state electrolyte all-solid-state battery,(2)research on solid-state polymer electrolyte and composite electrolyte,(3)electrode structure and material design and its effect on battery electrochemical performance,(4)interfacial phase problem of solid-state electrolyte,(5)lithium dendrite in lithium metal anode suppression problem and its application in lithium-sulfur batteries, etc., and(6)research on quasi-solid-state lithium metal batteries with high energy density and high safety.更多还原
