Determination of inelastic mean free path for solid polymer electrolytes: PTMC:LiBOB and PCL:LiBOB
Year: 2025
Type: article
Abstract: X-ray photoelectron spectroscopy (PES) has been widely applied in the field of battery studies. However, the lack of knowledge regarding the inelastic mean free path (IMFP) for studied systems limits the interpretation of spectroscopic results. In this work, the IMFP of poly(trimethylene carbonate) (PTMC), poly(ε-caprolactone) (PCL), and the solid polymer electrolytes consisting of lithium bis(oxalate)borate (LiBOB) together with PTMC or PCL has been determined using PES at a photoelectron kinetic energy of 8.7 keV. Additionally, the surface roughness of these films was investigated by atomic force microscopy and correlated with calculated IMFP values. Our studies reveal that the IMFP of solid polymer electrolytes is higher than that of pure polymers. The presented IMFPs provide references for future spectroscopic studies involving these materials.
