To solve this problem, we synthesize a composite using a gel polymer electrolyte and a separator as a functional membrane, coated with a layer of poly(ethylene oxide) (PEO) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). The PEO\/LiTFSI-coated polypropylene membrane slows the diffusion of polysulfides and stabilizes the liquid-state active material within the cathode region of the cell, while allowing smooth lithium-ion transfer. The lithium-sulfur cells with the developed membrane demonstrate a high charge-storage capacity of 1212 mA\u2219h g\u22121, 981 mA\u2219h g\u22121, and 637 mA\u2219h g\u22121 at high sulfur loadings of 2 mg cm\u22122, 4 mg cm\u22122, and 6 mg cm\u22122, respectively, and maintains a high reversible capacity of 534 mA\u2219h g\u22121 after 200 cycles, proving its ability to block the irreversible diffusion of polysulfides and to maintain the stabilized polysulfides as the catholyte for improved electrochemical utilization and stability. As a comparison, reference and control cells fabricated using a PEO-coated polypropylene membrane and a regular separator, respectively, show a poor capacity of 662 mA\u2219h g\u22121 and a short cycle life of 50 cycles.<\/p>\n","protected":false},"excerpt":{"rendered":"<h4>DOI:<\/h4>\n<div class=\"b-doi\">10.3390\/polym13040535<\/div>\n<h4>Authors:<\/h4>\n<div class=\"b-author\">Li-Ling Chiu, Sheng\u2010Heng Chung<\/div>\n<h4>Abstract:<\/h4>\n<div class=\"b-intro\">In lithium\u2013sulfur cells, the dissolution and relocation of the liquid-state active material (polysulfides) lead to fast capacity fading and low Coulombic efficiency, resulting in poor long-term electrochemical stability.
