Although metal\u2013organic frameworks (MOFs) improve the thermal stability of liquid electrolytes by capturing them in well-ordered sub-nanopores, interparticle voids between MOF particles readily absorb liquid electrolyte, obscuring our understanding of the intrinsic role of nanopores in directing Li\u207a transport. To address this challenge, we introduce a one-dimensional (1D) MOF model architecture that eliminates interparticle effects and enables direct observation of Li\u207a solvation and de-solvation dynamics. Comparative studies of 1D HKUST-1 and ZIF-8 uncover distinct transport behaviors, supported by both experimental measurements and neural network potential-based molecular dynamics simulations. Building on these insights, we construct a hierarchical core\u2013shell MOF architecture by integrating ZIF-8 (core) and HKUST-1 (shell) onto a hybrid fiber scaffold. This design harnesses the complementary strengths of both MOFs to achieve continuous ion pathways, directional Li\u207a conduction, and improved thermal and electrochemical resilience.<\/jats:p>","DOI":"10.1007\/s40820-025-01988-7","type":"journal-article","created":{"date-parts":[[2026,1,5]],"date-time":"2026-01-05T00:02:26Z","timestamp":1767571346000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Confining Li\u207a Solvation in Core\u2013Shell Metal\u2013Organic Frameworks for Stable Lithium Metal Batteries at 100\u00a0\u00b0C"],"prefix":"10.1007","volume":"18","author":[{"given":"Minh Hai","family":"Nguyen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeongmin","family":"Shin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mee-Ree","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quan Van","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JinHyeok","family":"Cha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sangbaek","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,1,5]]},"reference":[{"issue":"1","key":"1988_CR1","doi-asserted-by":"publisher","first-page":"4617","DOI":"10.1038\/s41467-023-40394-8","volume":"14","author":"G-R Zhu","year":"2023","unstructured":"G.-R.
