Abstract: Synchrotron X-ray and neutron diffraction facilities are very popular and indispensable scientific resources that provide powerful instruments and experimental techniques for both fundamental and applied researches around the world. X-rays and neutrons interact with matter in different and also complementary ways, and recently have been extensively used for studying energy storage materials at the electronic, atomic and molecular levels, and even extended to engineering scale. In this article, we will briefly introduce synchrotron X-ray and neutron scattering techniques and their difference, similarity and complementarity. Advantages of synchrotron high-energy X-rays will also be presented. The unique and powerful capacity of neutron scattering for hydrogen storage material study will be shown. We also present some examples of in-situ/operando study of the atomic structure evolution of Na1–δNi1/3Fe1/3Mn1/3O2 and LiNi0.5Mn1.5O4 active electrode materials during synthesis and electrochemical intercalation for sodium ion battery and lithium ion battery. Finally, the future perspectives of synchrotron X-ray and neutron diffraction techniques in the field of materials science for energy storage technology will be discussed.
