The current systems are nearing their capacity limits due to the reliance on conventional liquid electrolytes, which are fraught with stability and safety concerns, prompting the exploration of solid-state electrolytes, which enable the integration of metal electrodes. Solid-state sodium-ion batteries emerge as an appealing option by leveraging the abundance, low cost, and sustainability of sodium. However, low ionic conductivity and high interfacial resistance currently prevent their widespread adoption. This study explores polyvinyl-based polymers as wetting agents for the NASICON-type NZSP (Na3Zr2Si2PO12) solid electrolyte, resulting in a combined system with enhanced ionic conductivity suitable for Na-ion solid-state full cells. Electrochemical impedance spectroscopy (EIS) performed on symmetric cells employing NZSP paired with different wetting agent compositions demonstrates a significant reduction in interfacial resistance with the use of poly(vinyl acetate)\u2014(PVAc-) based polymers, achieving an impressive ionic conductivity of 1.31 mS cm\u22121 at room temperature, 63.8% higher than the pristine material, notably reaching 7.36 mS cm\u22121 at 90 \u00b0C. These results offer valuable insights into the potential of PVAc-based polymers for advancing high-performance solid-state sodium-ion batteries by reducing their total internal resistance.<\/jats:p>","DOI":"10.3390\/batteries10050157","type":"journal-article","created":{"date-parts":[[2024,5,3]],"date-time":"2024-05-03T09:39:47Z","timestamp":1714729187000},"page":"157","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Ionic Conductivity Analysis of NASICON Solid Electrolyte Coated with Polyvinyl-Based Polymers"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-3087-4163","authenticated-orcid":false,"given":"Tiago Afonso","family":"Salgueiro","sequence":"first","affiliation":[{"name":"Associate Laboratory for Energy, Transports and Aerospace (LAETA\/INEGI), Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"},{"name":"Institute of Physics and Advanced Materials, Nanotechnology and Photonics (IFIMUP), Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6934-490X","authenticated-orcid":false,"given":"Rita Carvalho","family":"Veloso","sequence":"additional","affiliation":[{"name":"Institute of Physics and Advanced Materials, Nanotechnology and Photonics (IFIMUP), Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0494-3009","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Ventura","sequence":"additional","affiliation":[{"name":"Institute of Physics and Advanced Materials, Nanotechnology and Photonics (IFIMUP), Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9890-5101","authenticated-orcid":false,"given":"Federico","family":"Danzi","sequence":"additional","affiliation":[{"name":"Associate Laboratory for Energy, Transports and Aerospace (LAETA\/INEGI), Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8839-0052","authenticated-orcid":false,"given":"Joana","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Associate Laboratory for Energy, Transports and Aerospace (LAETA\/INEGI), Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"},{"name":"Institute of Physics and Advanced Materials, Nanotechnology and Photonics (IFIMUP), Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,3]]},"reference":[{"key":"ref_1","first-page":"100928","article-title":"Concerns about lithium extraction: A review and application for Portugal","volume":"8","author":"Chaves","year":"2021","journal-title":"Extr.
