title: Storage of potassium ions in layered vanadium pentoxide nanofiber electrodes for aqueous pseudocapacitors.
abstract: Spaced out: This paper investigates potassium-ion storage in vanadium pentoxide nanofibers (VNFs, K0.33 V2 O5 ) with a layered architecture. In situ XRD experiments reveal that the interplanar space of VNF expands/contracts upon extraction/insertion of potassium ions during the redox process.
