CoO2 is synthesized by converting the quasi‐1D crystal structure of bulk Ca3Co2O6 via a hydrothermal treatment. The resulting nanostructures are predominantly nanoscrolls with very thin walls, which exhibit long‐term stability. A detailed structural investigation reveals that the CoO2 is found to crystallize in monoclinic form, similar to the related CaCoO2‐CoO2 misfit structure. Individual nanoscrolls are characterized electrically and show a p‐type semiconducting nature with a high current‐carrying capacity of 4·105 A cm−2 and an extremely high breakdown voltage of up to 270 kV cm−1. The results demonstrate the possibility to stabilize meta‐stable materials in low‐dimensional forms and a promising application of the nanoscrolls as interconnect in high‐voltage electronic circuitry. 000145153 536__ $$9info:eu-repo/grantAgreement/ES/AEI/CEX2023-001286-S$$9info:eu-repo/grantAgreement/ES/DGA/E13-23R$$9info:eu-repo/grantAgreement/EC/H2020/823717/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM3$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 823717-ESTEEM3$$9info:eu-repo/grantAgreement/EC/H2020/881603/EU/Graphene Flagship Core Project 3/GrapheneCore3$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 881603-GrapheneCore3$$9info:eu-repo/grantAgreement/EC/H2020/889546/EU/Properties of nanomaterials made from misfit-layered compounds revealed by electron microscopy and simulations/PROMISES$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 889546-PROMISES$$9info:eu-repo/grantAgreement/ES/MICINN/PID2019-104739GB-I00 000145153 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000145153 590__ $$a4.4$$b2024 000145153 592__ $$a1.154$$b2024 000145153 591__ $$aCHEMISTRY, MULTIDISCIPLINARY$$b79 / 239 = 0.331$$c2024$$dQ2$$eT2 000145153 593__ $$aMechanics of Materials$$c2024$$dQ1 000145153 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b174 / 460 = 0.378$$c2024$$dQ2$$eT2 000145153 593__ $$aMechanical Engineering$$c2024$$dQ1 000145153 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000145153 700__ $$aRoy, Kankona Singha 000145153 700__ $$0(orcid)0000-0002-2071-9093$$aArenal, Raúl 000145153 700__ $$aPanchakarla, Leela S. 000145153 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
