We apply this method to synthesize fulleride superconductors via Rb+ intercalation into a C60 film. During the intercalation, we monitor the stoichiometry via UHV-Raman spectroscopy and probe superconductivity via transport measurements. An increase of the superconducting transition temperature from 7.0 K to 14.5 K is observed when the stoichiometry is tuned from Rb2.7C60 to Rb3C60. In our experiment, an ionic Rb+ flux into the host material is induced by an applied electronic current via a Butler–Volmer-type mechanism. Electro-intercalation captivates through improved stoichiometric precision, the ability to smoothly vary stoichiometry via duration of current application, and the absence of a lower limit of the volume of the host material. It represents a powerful concept for the on-chip synthesis of intercalated materials, battery research, and beyond."}],"doi":"10.1021/acsnano.6c02466","author":[{"last_name":"Shchukin","full_name":"Shchukin, Konstantin P.","first_name":"Konstantin P."},{"first_name":"Oliver N.","full_name":"Gallego Lacey, Oliver N.","last_name":"Gallego Lacey"},{"first_name":"Baptiste","orcid":"0000-0001-5524-596X","last_name":"Coquinot","id":"f8417bd4-f599-11ee-a482-b927e3ed1e8e","full_name":"Coquinot, Baptiste"},{"first_name":"Jacek","full_name":"Jakowski, Jacek","last_name":"Jakowski"},{"full_name":"Huang, Jingsong","last_name":"Huang","first_name":"Jingsong"},{"first_name":"Patrik","last_name":"Staudenmayer","full_name":"Staudenmayer, Patrik"},{"full_name":"Falke, Yannic","last_name":"Falke","first_name":"Yannic"},{"full_name":"Pandeya, Ram Prakash","last_name":"Pandeya","first_name":"Ram Prakash"},{"full_name":"Grüneis, Alexander","last_name":"Grüneis","first_name":"Alexander"}],"has_accepted_license":"1"},{"file":[{"date_created":"2026-07-23T11:40:34Z","content_type":"application/pdf","file_id":"22397","success":1,"file_name":"2026_AdvancedFunctionalMat_He.pdf","access_level":"open_access","file_size":5734587,"date_updated":"2026-07-23T11:40:34Z","checksum":"b102207b2343e6e7dba00870bfe362ea","creator":"dernst","relation":"main_file"}],"OA_place":"publisher","day":"15","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2026","tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png"},"type":"journal_article","article_type":"original","publication_status":"published","department":[{"_id":"MaIb"}],"dataavailabilitystatement":"The data that support the findings of this study are available from the cor-responding authors upon reasonable request.","isi":1,"language":[{"iso":"eng"}],"date_updated":"2026-07-23T11:42:17Z","month":"01","oa":1,"license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","acknowledgement":"The authors acknowledge support from the 2BoSS project of the ERA-MIN3 program with the Spanish grant number PCI2022-132985/AEI/10.13039/50110001103, and funding from Generalitat de Catalunya 2021SGR01581 and European Union NextGenerationEU/PRTR.

In this study, FeCoNiMoW HEAs are synthesized into either amorphous nanosheets (HEANS) or crystalline nanoparticles (HEANP), which are then used to catalyze the lithium–sulfur (Li–S) reaction of Li–S batteries (LSBs). Evaluations in symmetric cells, coin cells, and pouch cells reveal that HEANS significantly enhance LSB performance, achieving initial discharge capacities up to 1632 mAh g−1. The batteries also exhibit excellent cycling stability over 1000 cycles at 3Cand maintain high-rate performance up to 10C with a capacity of 614 mAh g−1. Comprehensive in situ analyses and density functional theory calculations demonstrate that amorphous HEANS provide more active sites, better ionic conductivity and stronger chemical interactions with lithium polysulfides (LiPS). These properties effectively suppress the shuttle effect, promote the complete S8 → Li2S conversion by reducing the impedance of the solid-electrolyte interphase, and accelerate the Li2S4 → Li2S2 step by lowering the nucleation energy barrier. Overall, this study highlights the superior catalytic properties of amorphous 2D HEAs in LSBs and offers new insights into the mechanisms of LiPS conversion.","lang":"eng"}],"title":"Amorphous high entropy alloy nanosheets enabling robust Li–S batteries","doi":"10.1002/adfm.202513859","has_accepted_license":"1","author":[{"last_name":"He","full_name":"He, Ren","first_name":"Ren"},{"full_name":"Lee, Seungho","id":"BB243B88-D767-11E9-B658-BC13E6697425","last_name":"Lee","orcid":"0000-0002-6962-8598","first_name":"Seungho"},{"full_name":"Ding, Yang","last_name":"Ding","first_name":"Yang"},{"last_name":"Huang","full_name":"Huang, Chen","first_name":"Chen"},{"last_name":"Lu","full_name":"Lu, Xuan","first_name":"Xuan"},{"last_name":"Zheng","full_name":"Zheng, Lirong","first_name":"Lirong"},{"first_name":"Ao","full_name":"Yu, Ao","last_name":"Yu"},{"first_name":"Chaoyue","last_name":"Zhang","full_name":"Zhang, Chaoyue"},{"last_name":"Li","full_name":"Li, Canhuang","first_name":"Canhuang"},{"first_name":"Xiaoyu","full_name":"Bi, Xiaoyu","last_name":"Bi"},{"full_name":"Li, Yaqiang","last_name":"Li","first_name":"Yaqiang"},{"first_name":"Yaqi","full_name":"Liao, Yaqi","last_name":"Liao"},{"last_name":"Li","full_name":"Li, Junshan","first_name":"Junshan"},{"full_name":"Ostovari Moghaddam, Ahmad","last_name":"Ostovari Moghaddam","first_name":"Ahmad"},{"last_name":"Yernar","full_name":"Yernar, Salimov","first_name":"Salimov"},{"first_name":"Ying","last_name":"Xu","full_name":"Xu, Ying"},{"first_name":"Maria","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","last_name":"Ibáñez"},{"first_name":"Chaoqi","last_name":"Zhang","full_name":"Zhang, Chaoqi"},{"first_name":"Linlin","full_name":"Yang, Linlin","last_name":"Yang"},{"first_name":"Yingtang","last_name":"Zhou","full_name":"Zhou, Yingtang"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"}]}]
