Effects of differently sized and shaped active and passive Filler for PVDF-HFP CPEs in All Solid-State Lithium-Ion Batteries — •Daniel Karlinger, Yuxin Liang, and Peter Müller-Buschbaum — TUM School of Natural Sciences, Chair for Functional Materials, Graching, Germany

All-solid-state lithium-ion batteries are regarded as highly promising due to their enhanced safety and potentially higher energy density compared to conventional cells with liquid electrolytes. In this project, solid polymer electrolytes based on PVDF-HFP are investigated with the aim of improving ionic conductivity and overall electrochemical performance. The approach is to incorporate combinations of ac tive and passive fillers to tailor the material properties. Conductivity and mechanical stability will be systematically examined with cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), X ray diffraction (XRD) and other methods, in order to identify opti mized compositions for solid-state battery applications.
