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.

“…When the X-ray tomography technique is used, a series of X-ray images at different angles are recorded (the sample is rotated along an axis that is perpendicular to the incident X-rays) and then reconstructed by computer to produce the 3D images 58 . This X-ray tomography technique using synchrotron X-ray sources has been applied to the in situ/operando studies on dynamic 3D morphological changes during electrochemical reactions.…”

Lithium-ion battery (LIB) technology is the most attractive technology for energy storage systems in today's market. However, further improvements and optimizations are still required to solve challenges such as energy density, cycle life, and safety. Addressing these challenges in LIBs requires a fundamental understanding of the reaction mechanisms in various physical/chemical processes during LIB operation. Advanced in situ/operando synchrotron-based X-ray characterization techniques are powerful tools for providing valuable information about the complicated reaction mechanisms in LIBs. In this review, several state-of-the-art in situ/operando synchrotron-based X-ray techniques and their combination with other characterization tools for battery research are introduced. Various in situ cell configurations and practical operating tips for cell design and experimental set-ups are also discussed.

“…We used TXM-Wizard, a software developed and described by Liu et al (2011Liu et al ( , 2016, to reconstruct the 3-D spatial distribution of the different components starting from the 2-D projections. The algorithm used was the iterative algebraic reconstruction technique (ART) with 20 iterations (beyond 20 iterations, the quality of the reconstructed images did not improve significantly).…”

In the near future, a new generation of sample return missions (Hayabusa2, OSIRIS‐REx, MMX, etc.) will collect samples from small solar system bodies. To maximize the scientific outcome of laboratory studies and minimize the loss of precious extraterrestrial samples, an analytical sequence from less destructive to more destructive techniques needs to be established. In this work, we present a combined X‐ray and IR microtomography applied to five Itokawa particles and one fragment of the primitive carbonaceous chondrite Paris. We show that this analytical approach is able to provide a 3‐D physical and chemical characterization of individual extraterrestrial particles, using the measurement of their 3‐D structure and porosity, and the detection of mineral and organic phases, and their spatial co‐localization in 3‐D. We propose these techniques as an efficient first step in a multitechnique analytical sequence on microscopic samples collected by space missions.
