Ag nanoparticles (NPs) were produced in an aqueous polyvinyl pyrrolidone (PVP) solution by using AgNO3 precursor. A viscous lithium acetate/cobalt acetate/polyvinylalcohol/water (LiAc/(CoAc)(2)/PVA/water) solution was prepared separately. A Ag NPs/PVP/water solution was prepared and added to this viscous solution and magnetically stirred to obtain the final homogeneous electrospinning solution. After establishing the proper electrospinning conditions, as-spun precursor Ag/LiAc/Co(Ac)(2)/PVA/PVP NFs were formed and calcined in air at a temperature of 600 degrees C for 3 h to form well-crystallized porous Ag/LiCoO2 NFs. Various analytical characterization techniques such as UV-vis, SEM, TEM, TGA, XRD, and XPS were performed to analyze Ag NPs, as-spun and calcined NFs. It was established that Ag NPs in the precursor Ag/LiAc/Co(Ac)(2)/PVA/PVP NFs are highly self-aligned as a result of the behavior of Ag in the electric field of the electrospinning setup and the interaction of Ag ions with Li and Co ions in the NE Ag/LiCoO2 NFs exhibit a nanoporous structure compared with undoped LiCoO2 NFs because the atomic radius of Ag is larger than the radius of Co and Li ion; thus, no substitution between Ag and Li or Ag and Co atoms occurs, and Ag NPs are located at the interlayer of LiCoO2 while some are left in the fiber.eninfo:eu-repo/semantics/closedAccessChemistryPhysicsNanostructuresSol-gel growthCrystal structureMicrostructureElectrochemical performanceSurface-modificationOptical-propertiesCathode materialsDoped LICOO2LithiumXpsMechanismsFilmsAcidCalcinationCobaltCrystal structureElectric fieldsElectrospinningIonsLithiumMicrostructureNanofibersNanostructuresSol-gel processSol-gelsAnalytical characterizationElectrospinning setupsElectrospinning techniquesNanoporous structuresPolyvinyl pyrrolidoneSynthesis and characterizationsViscous solutionSilverArticle0003235900000062-s2.0-84881043161153815457411Chemistry, multidisciplinaryPhysics, condensed matterLithium-ion Batteries; Electrode; Electrochemical Properties
