Kum, KS Song, MK Kim, YT Kim, HS Cho, BW Rhee, HW 2024-01-21T06:05:17Z 2024-01-21T06:05:17Z 2021-09-05 2004-11-30 0013-4686 https://pubs.kist.re.kr/handle/201004/137037 A miscible blend solution of poly(ethylene glycol diacrylate) (PEGDA)/poly(vinylidene fluoride) (PVdF)/poly(methyl methacrylate) (PMMA) was crosslinked on polypropylene (PP) separator by UV-irradiation. PEGDA/PVdF/PMMA(EN/M)-coated electrolytes showed much better liquid electrolyte uptaking and retention than PEGDA/PP composite electrolyte because viscous ternary blend solution was more compatible with electrolyte system. Gel-coated membranes (GCE) containing a mixed lithium salts of LiPF6/LiCF3SO3 (10/1 (w/w)) showed slightly lower maximum conductivity than those containing only LiPF6, but their interfacial resistance much more stable than other salt compositions. In addition, it was found that gamma-Al2O3 filler improved interfacial stability. As a result, 8 cm x 13 cm MCMB/LiCoO2 cells composed of E/V/M-coated composite matrix and LiPF6/LiCF3SO3 (10/1 (w/w)) delivered 99.6% initial capacity after 100 cycles at C/2 rate.
