AB - In this study we present a novel method of lithium ion battery electrode sample preparation with a new type of epoxy impregnation,brominated (Br) epoxy, which is introduced here for the first time for this purpose and found suitable for focused ion beam scanningelectron microscope (FIB-SEM) tomography. The Br epoxy improves image contrast, which enables higher FIB-SEM resolution (3Dimaging), which is amongst the highest ever reported for composite LFP cathodes using FIB-SEM. In turn it means that the particlesare well defined and the size distribution of each phase can be analyzed accurately from the complex 3D electrode microstructureusing advanced quantification algorithms.The authors present for the first time a new methodology of contrast enhancement for 3D imaging, including novel advancedquantification, on a commercial Lithium Iron Phosphate (LFP) LiFePO4 cathode. The aim of this work is to improve the quality ofthe 3D imaging of challenging battery materials by developing methods to increase contrast between otherwise previously poorlydifferentiated phases. This is necessary to enable capture of the real geometry of electrode microstructures, which allows measurementof a wide range of microstructural properties such as pore/particle size distributions, surface area, tortuosity and porosity. Theseproperties play vital roles in determining the performance of battery electrodes.
