Abstract

High capacity redox active materials are the building blocks for batteries and modern electrochemical conversion devices. Last couple of decades has witnessed tremendous progress in the area of rechargeable batteries for transportation, grid storage and consumer applications.1 The talk will provide an overview of the current R&D status of advanced batteries for electric vehicles followed by deep dive analysis of lithium-ion battery electrodes using X-ray synchrotron, micro-Raman and neutron spectroscopic and imaging methods. Specifically, the talk will cover recent work related to applying X-ray transmission imaging combined with near edge absorption spectroscopy (XANES) to study the evolution of chemical oxidation state of the transition metal (TM) cations accompanied by changes in the particle morphology for a number of lithium-ion cathode systems such as lithium-manganese rich NMC cathodes (LMR-NMC) and high capacity Li2Cu0.5Ni0.5O2 cathodes.2-4 Ex-situ and in-situ Raman and neutron imaging methods for studying micron scale inhomogeneties associated with high capacity battery electrodes such as silicon-graphite will also be presented.5-7 1.
