Synchrotron x-ray and neutron facilities are very popular and indispensable scientific resources and provide powerful instruments and experimental techniques for both fundamental and applied researches. X-rays and neutrons interact with matter in different ways, thus are often used as complementary tools for studying materials at the electronic, atomic and molecular levels. We have been utilizing synchrotron and neutron diffraction techniques to investigate a variety of materials for energy storage and conversion applications. In this talk, we will discuss the difference and similarity of synchrotron x-rays and neutrons, and their complementary use in materials research. We will present our recent results on in-situ/operando characterization of advanced materials for rechargeable batteries, ranging from material synthesis to safety. The knowledge of the atomic-level structures and electronic states and their evolution in realistic conditions provides important information for better understanding of material properties and for further improvement of their performance and functionality. We will also discuss some challenging issues in battery materials characterization.
