Challenges, such as high volume expansion of the S-cathode upon discharge, low electronic conductivity of S as active material and herewith limited rate capability as well as the shuttling of polysulfides (PSs) as intermediates often impede the cycle stability and practical application of Na-S batteries. Sulfurized poly(acrylonitrile) (SPAN) inherently inhibits the shuttling of PSs and shows compatibility with carbonate-based electrolytes, however, its exact redox mechanism remained unclear to date. Herein, we implement a commercially available and simple electrolyte into the Na-SPAN cell chemistry and demonstrate its high rate and cycle stability. Through the application of in situ techniques utilizing electronic impedance spectroscopy (EIS) and X-ray absorption spectroscopy (XAS) at different depths of charge and discharge, an insight into SPAN’s redox chemistry is obtained.","lang":"eng"}],"article_number":"010526","doi":"10.1149/1945-7111/acb2fa","issue":"1","publication_status":"published","publication_identifier":{"issn":["0013-4651","1945-7111"]},"department":[{"_id":"35"},{"_id":"306"}],"_id":"40981","title":"Understanding the Redox Mechanism of Sulfurized Poly(acrylonitrile) as Highly Rate and Cycle Stable Cathode Material for Sodium-Sulfur Batteries","volume":170,"citation":{"bibtex":"@article{Kappler_Tonbul_Schoch_Murugan_Nowakowski_Lange_Klostermann_Bauer_Schleid_Kästner_et al._2023, title={Understanding the Redox Mechanism of Sulfurized Poly(acrylonitrile) as Highly Rate and Cycle Stable Cathode Material for Sodium-Sulfur Batteries}, volume={170}, DOI={<a href=\"https://doi.org/10.1149/1945-7111/acb2fa\">10.1149/1945-7111/acb2fa</a>}, number={1010526}, journal={Journal of The Electrochemical Society}, publisher={The Electrochemical Society}, author={Kappler, Julian and Tonbul, Güldeniz and Schoch, Roland and Murugan, Saravanakumar and Nowakowski, Michał and Lange, Pia Lena and Klostermann, Sina Vanessa and Bauer, Matthias and Schleid, Thomas and Kästner, Johannes and et al.}, year={2023} }","short":"J.
