摘要：
Spaced out: This paper investigates potassium-ion storage in vanadium pentoxide nanofibers (VNFs, K0.33V2O5) with a layered architecture. Insitu XRD experiments reveal that the interplanar space of VNF expands/contracts upon extraction/insertion of potassium ions during the redox process. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
