Abstract:<\/h4>\n
In this study, we evaluated the properties exhibited by a composite solid electrolyte (CSE) prepared via<\/i> tailoring the particle size of an active filler, Li6.4<\/sub>La3<\/sub>Zr1.4<\/sub>Ta0.6<\/sub>O12<\/sub> (LLZTO). The average particle size was reduced to 2.53 \u03bcm via<\/i> ball milling and exhibited a specific surface area of 3.013 m2<\/sup> g-1<\/sup>. Various CSEs were prepared by combining PEO and LLZTO\/BM-LLZTO. The calculated lithium ionic conductivity of the BM-LLZTO CSE was 6.0 \u00d7 10-5<\/sup> S cm-1<\/sup>, which was higher than that exhibited by the LLZTO CSE (4.6 \u00d7 10-5<\/sup> S cm-1<\/sup>). This result was confirmed via<\/i> 7<\/sup>Li nuclear magnetic resonance (NMR) analysis, during which lithium-ion transport pathways varied as a function of the particle size. NMR analysis showed that when BM-LLZTO was used, the migration of Li ions through the interface occurred at a fast rate owing to the small size of the constituent particles. During the Li\/CSEs\/Li symmetric cell experiment, the BM-LLZTO CSE exhibited lower overvoltage characteristics than the LLZTO CSE. A comparison of the characteristics exhibited by the LFP\/CSEs\/Li cells confirmed that the cells using BM-LLZTO exhibited high discharge capacity, rate performance, and cycling stability irrespective of the CSE thickness.<\/p>\n","protected":false},"excerpt":{"rendered":"DOI: 10.1039\/d1ra06210g Authors: Young-Woong Song, Kookjin Heo, Jongkwan Lee, Dahee Hwang, Minyoung Kim, Su Jin Kim, Jaekook Kim, Jinsub Lim Abstract: In this study, we evaluated the properties exhibited by a composite solid electrolyte (CSE) prepared via tailoring the particle size of an active filler, Li6.4La3Zr1.4Ta0.6O12 (LLZTO).
