Herein, a series of substrate-free Li salt-grafted cholesteric liquid crystal elastomers (CLCE) with tunable helical pitches and spiral orientation were fabricated, and quasi-solid electrolyte membranes were obtained through plasticization. It was found that samples with the smallest helical pitch delivered the highest lithium-ion transference number irrespective of the spiral orientation. The optimal CLCE electrolyte membrane achieved a lithium-ion transference number of 0.94, exhibiting characteristic single-ion conductivity. Moreover, after adding small amount of extra free Li salt, the prepared electrolyte membrane delivered a room-temperature ionic conductivity of 2.6 \u00d7 10\u22124 S\u00b7cm\u22121, an electrochemical stability window of 5.2 V and stable cycling performance, providing new insights into the design of high-performance safe quasi-solid lithium-ion batteries.<\/jats:p>","DOI":"10.3390\/molecules31162879","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T10:22:52Z","timestamp":1787048572000},"page":"2879","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cholesteric Liquid Crystal Elastomer-Based Single-Ion Conductor for Advanced Quasi-Solid Electrolyte Membranes"],"prefix":"10.3390","volume":"31","author":[{"given":"Tangqi","family":"Hu","sequence":"first","affiliation":[{"name":"Jiangsu Key Laboratory of Advanced Functional Polymer Materials, Department of Polymer Science and Engineering, College of Chemistry, Chemical Engineering and Materials Science, Soochow University, Suzhou 215123, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junxian","family":"Fu","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Advanced Functional Polymer Materials, Department of Polymer Science and Engineering, College of Chemistry, Chemical Engineering and Materials Science, Soochow University, Suzhou 215123, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0185-7471","authenticated-orcid":false,"given":"Yonggang","family":"Yang","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Advanced Functional Polymer Materials, Department of Polymer Science and Engineering, College of Chemistry, Chemical Engineering and Materials Science, Soochow University, Suzhou 215123, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4477-7490","authenticated-orcid":false,"given":"Yi","family":"Li","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Advanced Functional Polymer Materials, Department of Polymer Science and Engineering, College of Chemistry, Chemical Engineering and Materials Science, Soochow University, Suzhou 215123, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"652","DOI":"10.1038\/451652a","article-title":"Building better batteries","volume":"451","author":"Armand","year":"2008","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2201718","DOI":"10.1002\/advs.202201718","article-title":"Ionic Conduction in Polymer-Based Solid Electrolytes","volume":"10","author":"Li","year":"2023","journal-title":"Adv.
