“…On the other hand, desired and optimized battery performance of electrode particles can be achieved from engineering size and morphology of electrode particles and fabricating nanostructured units (e.g., mesopores, arrays, etc.) . As a result, the capability of probing large‐scale structure, compensatory to the atomic structure, is important to the battery investigation and design.…”

“…However, for SAXS, the decrease of beam energy brings other challenges, e.g., the weak penetrability that is of particular importance for the in situ battery types of research. Taking this into account, a moderate energy range of 10–20 keV has been applied for SAXS experiments . Neutrons possess a larger penetration depth than X‐rays so that the SANS patterns can be collected with a broader band of wavelength λ up to 20–30 Å .…”

“…The beam size for a typical SAXS experiment is focused to 250–300 μm in diameter. For the in situ battery kinds of research, custom‐designed coin cells, transparent tube cells, or the APMIX cells are proper for the SAXS measurements (Figure ). A typical instrument layout for SANS measurements is shown in Figure b .…”

Knowledge of atomic interactions with high‐energy photons or particles has opened a window to the microscopic structures of materials. In particular, X‐rays and neutrons interact with electrons and nuclei of atoms in different ways, which enables their complementary scattering, spectroscopic, and imaging capabilities for structural characterizations. In the past decades, techniques based on X‐ray and neutron interactions, capable of being time‐resolved and combined, have been well developed for encoding structures in various length, elemental and temporal levels, and, in turn, have ignited breakthroughs in the field of battery science and engineering. Herein are reviewed the advanced in situ X‐ray and neutron techniques for studying lithium‐ion batteries, which offer dynamic observations of chemical, electronic, and geometric changes during realistic battery operations. For each of the techniques, with a brief description of the theory on account of characterizing principles is given (i.e., scattering, excitation, and emission), followed by an introduction of operando methodologies including instruments, setups, and cell designs employed in synchrotron and neutron beamlines. Finally, a few practical examples are presented to demonstrate the applicability of these techniques in studying Li‐ion batteries, with a particular emphasis on each of their structural sensitivities at various time, elemental, and length levels.

Understanding the electrochemical processes responsible for energy storage in batteries is critical for designing of next-generation batteries. The conventional laboratory-scale characterization instruments provide limited information required for better understanding of electrochemical reaction mechanisms. Synchrotron radiations have very high brilliance and broad energy range extending from far-IR through the hard X-ray region. The availability of synchrotron radiation is driving technical and theoretical advances in scattering and spectroscopic techniques from last couple of decades. These advances in synchrotron radiation-based characterization techniques have made it possible to study the underpinning issues of energy storage materials. An electrochemical road map based on much more knowledge-driven approach can be drawn by utilizing synchrotron-based element-specific spectroscopic as well as scattering techniques. Herein, we introduce various scenarios where synchrotron radiation-based characterization methods provide inherent advantages and flexibility in obtaining detailed mechanistic information along with structural studies.
