“…Wolf et al (2017) have summarized the current techniques visualizing the electrochemical behavior in battery materials. X-ray powder diffraction (XRD) and X-ray spectroscopy provide the ensemble structure information and oxidation state of a specific chemical element for operando battery materials (Ren & Zuo, 2018). The full-field transmission X-ray microscope combined with X-ray absorption near the absorption edge gives local structural and oxidation state information in the field of view (Wang et al, 2013).…”

Bragg coherent X‐ray diffraction imaging has become valuable for visualization of the structural, morphological and strain evolution of crystals in operando electrode materials. As the electrode material particles (either in a single‐crystal form or an aggregation form of single crystals) are evenly dispersed and randomly oriented in the electrode laminate, the submicrometer‐sized coherentX‐ray beam can be used to probe the local properties of electrode material crystals using two approaches. Coherent multi‐crystal diffraction provides collective structural information of phase transitions in tens of crystals simultaneously as well as the individual behavior from single crystals, which are oriented at the Bragg condition in the X‐ray illumination volume. Bragg coherent diffractive imaging enables one to monitor the evolution of the morphology and strain in individual crystals. This work explores and highlights the Bragg coherent X‐ray diffraction measurements of battery electrode materials in operando conditions at the 34‐ID‐C beamline at the Advanced Photon Source. The experiment is demonstrated with NaNi1/3Fe1/3Mn1/3O2, a sodium‐ion cathode material loaded in a half cell. The paper will discuss, in detail, the beamline setup, sample mounting and handling, alignment strategies and the data acquisition protocols.

“…In recent years, the rapid development of the global economy has accelerated energy consumption. The overdependence on dominant fossil fuels today has caused environmental problems, which raises our interest in clean energy resources, such as solar and wind energy. However, the intermittency of such renewable energy hinders its practical conversion to electrical energy .…”

With the remarkably large theoretical specific capacity of silicon (Si), Si‐based rechargeable lithium‐ion batteries (LIBs) have attracted great interest, as they are expected to meet the growing demand for large‐scale energy storage devices, electric vehicles, and portable electronic devices with high energy density. However, the Si‐based LIB faces great challenges due to the cyclic volume changes induced by Si, which lead to considerable capacity fading. To facilitate the use of high‐performance LIBs enabled by Si‐based anodes, understanding the fading mechanism is necessary. In this regard, various advanced characterization methods have been developed to reveal the fading mechanism and to develop a modification strategy associated with compositional and structural evolution. In this review, the general understanding of the fading mechanism and the technical specifications of Si‐based LIBs are discussed. The recent progress in advanced characterization methods for Si‐based LIBs is summarized with respect to the achievements in compositional and structural interpretation. Several possible future research directions for Si‐based LIBs and the expected development trends in relevant characterization methods are also discussed.

“…Those achievements would not, however, be possible if experimental research schemes involving advanced measurements, cell designs, and experimental protocols had not been developed, enabling maximal informative power from minimum amount of experiments. [2][3][4][5][6][7][8][9][10][11] Today, aqueous metal-ion batteries are electrochemical methods and battery tests with quartz crystal microbalance measurements that are performed in operando. In this new cell design, multiple electrodes can be synthesized and characterized individually, and afterward can be operated together in order to measure a full battery using only a single setup.…”

Recently, aqueous metal‐ion batteries have attracted significant attention, as they can provide rather efficient and safe solutions with regard to large‐scale renewable energy storage applications. However, better fundamental understanding of the electrode and electrolyte materials for these devices is necessary to advance their performance. The research methodology for well‐known types of batteries, such as lithium‐ion batteries, relies on numerous available cell designs and protocols. Fundamental research in the field of aqueous metal‐ion batteries, on the contrary, still requires the development of new, original, and versatile cells as well as procedures to improve the efficiency and informative power of experiments. In this work, a concept for the research cell design dedicated to the aqueous metal‐ion batteries is presented, enabling advanced electrochemical characterization of model electrode materials (including the mass changes of the active electrodes). Electrodes based on Prussian blue analogs, which are state‐of‐the‐art electrode materials for aqueous Na‐ion batteries, are used to demonstrate the concept.
