Abstract
A Synchrotron Light Research Institute (SLRI, Public Organization) is a national laboratory. It is located at Nakhon Ratchasima, Thailand. SLRI provides synchrotron light for structural analysis, research, and development. Currently, SLRI has 10 beamlines and 12 end stations for scattering, diffraction, spectroscopy, imaging, and microfabrication techniques. The status of XAS beamlines has 5 end-stations (BL1.1W, 2.2, 5.2, 7.2W and 8). Recently, the Operando-XAS is performed using beamline 2.2 (Time-resolved X-ray Absorption Spectroscopy, TRXAS) which the main optical component is an energy-dispersive monochromator (EDM). Using the energy-dispersive scheme with a position-sensitive detector, the beam size at the sample position can be small and have a fast detection speed in the XAS spectrum. In this presentation, we will summarize the developments of the experimental tools to characterize energy storage materials (e.g. Lithium-ion batteries, Zn-ion batteries, and H2-production process) and give examples of the capability of the instruments via studies of materials performed at the XAS beamlines in Thailand.
