Fourier Transform Infrared Spectroscopy revealed structural changes in Polyvinylidene fluoride during slurry preparation, whereas polyethylene oxide remained unaffected. X-ray photoelectron spectroscopy analysis confirmed the chemical and electrochemical stability of polyethylene oxide, while NaF formation provided clear evidence for Polyvinylidene fluoride defluorination and its further degradation during cycling. Galvanostatic charge/discharge measurements showed an improvement in capacity retention of 5.8% after 100 cycles for polyethylene oxide -based electrodes compared to Polyvinylidene fluoride, demonstrating the detrimental impact of Polyvinylidene fluoride degradation on electrochemical performance. These findings highlight the importance of developing chemically stable binder systems for sodium-ion batteries. Dataset: This dataset contains electrochemical measurements, FT-IR, PXRD and XPS to investigate the two different binder Systems PVDF and PEO. The dataset is organized into the following folders: Electrochemical experiments: Cyclovoltammetry and galvanostatic charge/discharge experiments were conducted. Data are stored in the folder Electrochemistry. FT-IR: FI-IR spectroscopy were performed using a Bruker spectrometer (model Vertex 80v). The background was determined in each measurement with an empty sample holder and subtracted from the raw data. Data are stored in the folder FT-IR. PXRD: X-ray diffraction (XRD) experiments were performed using an Empyrean diffractometer (Pananalytical, Almelo, Netherlands). The corresponding diffractograms are stored in the folder PXRD. TGA: Thermogravimetric Analysis (TGA) was performed on Netzsch STA 449F1. The corresponding measurement are stored in the folder TGA. XPS: X-ray photoelectron spectroscopy (XPS) for the binder study PVDF/PEO was performed on a NEXSA G2 photoelectron spectrometer (Thermo Fisher Scientific Inc.) with a monochromatic Al-Kα X-ray source (hν = 1486.6 eV) and were carried out by nanoAnalytics GmbH (Germany). Data are stored in the folder XPS. For each dataset, detailed experimental procedures and relevant information are provided in the respective folder's ReadMe file.1_1_PVDF_1_5_4_0V_0_02mV_s_CV.txtCV measurement PVDFtext/plain1_NFMO_powder.txtFT-IR measurement NFMO powdertext/plain1_PEO_1_5-4_0V_0_02mV_s_CV.txtCV measurement PEOtext/plain2_1_PEO_1_5-4_0V_halfcell_Crate_test.txtCrate test PEOtext/plain2_purePEO_powder.txtFT-IR measurement PEO powdertext/plain2_PVDF_1_5-4_0V_halfcell_Crate_test.txtCrate test PVDFtext/plain3_purePVDF_powder.txtFT-IR measurement PVDF powdertext/plain3_PVDF_PEO_1_5-4_0V_0_05C_halfcell_longterm.txtLongterm measurement PEO and PVDFtext/plain4_PEO_Slurry.txtFT-IR measurement PEO Slurrytext/plain5_PVDF_Slurry.txtFT-IR measurement PVDF Slurrytext/plainAL2O3_5_55deg.xyPXRD of Al2O3application/octet-streamCarbonBlack_C1s.txtXPS measurement of carbon black C1stext/plainCarbonBlack_F1s.txtXPS measurement of carbon black F1stext/plainCarbonBlack_O1s.txtXPS measurement of carbon black O1stext/plainNFMO_5_55deg.xyPXRD of NFMOapplication/octet-streamNFMO_Powder_C1s.txtXPS measurement NFMO powder C1stext/plainNFMOpowder_electrolyte_5_55deg.xyPXRD of NFMO powder and electrolyteapplication/octet-streamNFMO_Powder_O1s.txtXPS measurement NFMO powder O1stext/plainPEO_1cycle_C1s.txtXPS measurment PEO first cycle C1stext/plainPEO_1cycle_F1s.txtXPS measurment PEO first cycle F1stext/plainPEO_1cycle_O1s.txtXPS measurment PEO first cycle O1stext/plainPEO_1cycle_P2p.txtXPS measurment PEO first cycle P2ptext/plainPEO_cathode_C1s.txtXPS measurement of PEO cathode C1stext/plainPEO_cathode_F1s.txtXPS measurement of PEO cathode F1stext/plainPEO_cathode_O1s.txtXPS measurement of PEO cathode O1stext/plainPEO_OCV_C1s.txtXPS measurement PEO OCV C1stext/plainPEO_OCV_F1s.txtXPS measurement PEO OCV F1stext/plainPEO_OCV_O1s.txtXPS measurement PEO OCV O1stext/plainPEO_OCV_P2p.txtXPS measurement PEO OCV P2ptext/plainPEO_Powder_C1s.txtXPS measurements PEO powder C1stext/plainPEO_Powder_O1s.txtXPS measurements PEO powder O1stext/plainPEO_Slurry_5_55deg.xyPXRD of PEO slurryapplication/octet-streamPEO_Slurry_electrolyte_5_55deg.xyPXRD of PEO slurry and electrolyteapplication/octet-streamPVDF_1_5V_C1s.txtXPS measurement PVDF cycled until 1.5V C1stext/plainPVDF_1_5V_F1s.txtXPS measurement PVDF cycled until 1.5V F1stext/plainPVDF_1_5V_O1s.txtXPS measurement PVDF cycled until 1.5V O1stext/plainPVDF_4_2V_C1s.txtXPS measurement PVDF charged until 4.2V C1stext/plainPVDF_4_2V_F1s.txtXPS measurement PVDF charged until 4.2V F1stext/plainPVDF_4_2V_O1s.txtXPS measurement PVDF charged until 4.2V O1stext/plainPVDF_cathode_C1s.txtXPS measurement PVDF cathode C1stext/plainPVDF_cathode_F1s.txtXPS measurement PVDF cathode F1stext/plainPVDF_cathode_O1s.txtXPS measurement PVDF cathode O1stext/plainPVDF_OCV_C1s.txtXPS measurement PVDF OCV C1stext/plainPVDF_OCV_F1s.txtXPS measurement PVDF OCV F1stext/plainPVDF_OCV_O1s.txtXPS measurement PVDF OCV O1stext/plainPVDF_Powder_C1s.txtXPS measurement PVDF powder C1stext/plainPVDF_Powder_F1s.txtXPS measurement PVDF powder F1stext/plainPVDF_Powder_O1s.txtXPS measurement PVDF powder O1stext/plainPVDF_Slurry_5_55deg.xyPXRD of PVDF slurryapplication/octet-streamPVDF_Slurry_electrolyte_5_55deg.xyPXRD of PVDF slurry and electrolyteapplication/octet-streamREADME.txttext/plainREADME.txtParameter files of PXRD measurementstext/plainREADME.txttext/plainREADME.txtDescription Description of conducted experiments text/plainREADME.txttext/plainREADME.txtDescriptiontext/plainREADME.txtExperimental description text/plainRietveld_Al2O3_NFMO_plot.txtFit data of Al2O3/NFMOtext/plainRietveld_Al2O3_NFMO_report.txtReport Al2O3text/plainRietveld_Al2O3_plot.txtFit data Al2O3text/plainRietveld_Al2O3_report.txtReport Al2O3text/plainRietveld_NFMO_Electrolyte_plot.txtFit data NFMO Electrolytetext/plainRietveld_NFMO_Electrolyte_report.txtReport NFMO Electrolytetext/plainRietveld_PEO_Slurry_Electrolyte_plot.txtFit data PEO Slurry Electrolytetext/plainRietveld_PEO_Slurry_Electrolyte_report.txtReport PEO Slurry Electrolytetext/plainRietveld_PEO_Slurry_plot.txtFit data PEO Slurrytext/plainRietveld_PEO_Slurry_report.txtReport PEO Slurrytext/plainRietveld_PVDF_Slurry_Electrolyte_plot.txtFit data PVDF Slurry Electrolytetext/plainRietveld_PVDF_Slurry_Electrolyte_report.txtReport PVDF Slurry Electrolytetext/plainRietveld_PVDF_Slurry_plot.txtFit data PVDF Slurrytext/plainRietveld_PVDF_Slurry_report.txtReport PVDF Slurrytext/plainTGA_NFMO.txtTGA measurementtext/plain
