The polyvinylidene fluoride (PVDF) or polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) is gravure-coated, and the pores are fabricated based on online nonsolvent-induced phase separation (NIPS). N-methylpyrrolidone is used as a solvent, and deionized water or a methanol mixture thereof is exploited as a nonsolvent in NIPS. Scanning electron microscopy confirms that the polymer film is formed and that the pores are well developed. The thermal shrinkage decreased by 20.0% and 23.2% compared to that of the bare separator due to the coating of PVDF and PVDF-HFP, respectively. The R2R gravure coating scheme is proven to be fully functional to tailor the properties of lithium-ion battery separators.<\/jats:p>","DOI":"10.3390\/polym15204108","type":"journal-article","created":{"date-parts":[[2023,10,16]],"date-time":"2023-10-16T10:06:36Z","timestamp":1697450796000},"page":"4108","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Roll-to-Roll Gravure Coating of PVDF on a Battery Separator for the Enhancement of Thermal Stability"],"prefix":"10.3390","volume":"15","author":[{"given":"Gyuyoung","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Mechanical Design and Production Engineering, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-4909-089X","authenticated-orcid":false,"given":"Jin-Hee","family":"Noh","sequence":"additional","affiliation":[{"name":"Daegu Technopark, Daegu 41256, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Horim","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Mechanical Design and Production Engineering, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaehak","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Mechanical Design and Production Engineering, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7575-868X","authenticated-orcid":false,"given":"Dongjin","family":"Lee","sequence":"additional","affiliation":[{"name":"School of Mechanical and Aerospace Engineering, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"204","DOI":"10.1038\/s41928-018-0048-6","article-title":"How we made the Li-ion rechargeable battery","volume":"1","author":"Goodenough","year":"2018","journal-title":"Nat.
