"Using Synchrotron X-ray and Neutron Based Scattering as well as TXM and TEM Imaging Techniques to Study the New Cathode Materials for Batteries and Studies on Li Metal Anode Protections"
Abstract: The new results of using in situ and ex situ synchrotron based x-ray techniques, such as x-ray diffraction (XRD), x-ray absorption spectroscopy (XAS), transmission x-ray microscopy (TXM), in situ X-ray fluorescence (XRF) microscopy combined with X-ray absorption spectroscopy (XAS), as well as x-ray pair distribution function (XPDF) and neutron pair distribution function (NPDF) on advanced battery materials will be discussed. Studies on several new materials, such as high nickel content layer structured materials, Li-rich and Mn-rich materials as high energy density materials for Li-ion batteries and Li-metal batteries will be presented. The studies on Li-metal anode protections by new additives for electrolytes and polymer protection layer will be discussed.
