The global production landscape exhibits a substantial need for efficient and clean energy. Enhancing and advancing energy storage systems are a crucial avenue to optimize energy utilization and mitigate costs. Lithium batteries are the most effective and impressive energy utilization system at present, with good safety, high energy density, excellent cycle performance, and other advantages, occupying most of the market. However, due to the defects in the electrode material of the battery itself, the electrode will undergo the process of expansion, stress evolution, and electrode damage during electro-chemical cycling, which will degrade battery performance. Therefore, the detection of property changes in the electrode during electro-chemical cycling, such as the evolution of stress and the modulus change, are useful for preventing the degradation of lithium-ion batteries. This review presents a current overview of measurement systems applied to the performance detection of batteries’ electrodes, including the multi-beam optical stress sensor (MOSS) measurement system, the digital image correlation (DIC) measurement system, and the bending curvature measurement system (BCMS), which aims to highlight the measurement principles and advantages of the different systems, summarizes a part of the research methods by using each system, and discusses an effective way to improve the battery performance.

“…[ 172 ] During the lithiation process of graphite anode, the strain in the electrode plane is not linearly related to lithium ions concentration, and local stress will limit the diffusion of lithium ions and the lithiation of the electrode ( Figure 7 a). [ 173 ] A combination of micrometer level computed tomography and digital image correlation sensing technology are used to characterize the suppression of lithium dendrites by separators. [ 174 ] Also, it is discovered that the strain of solid electrolytes membrane mainly changes in the direction perpendicular to the electrode, indicating that the transportation of lithium ions in solid electrolyte is affected by local mechanical and current non‐uniformity (Figure 7b).…”

“…In addition to mapping topography, advanced AFM-based techniques can probe elastic modulus but are usually applied to soft or ultrathin materials, such as SEI layers.

“…A digital image correlation of electrodes coated with fluorescent silica nanoparticles to form the speckle pattern can be used to track the strain field during electrochemical reactions. 410,411 It is noteworthy that mechanical characterization of some energy materials sometimes requires original assumptions (e.g., about homogeneity, isotropy, and absence of microstructural features) to be relaxed. For example, wafer curvature, originally developed for homogeneous films, has been used in combination with X-ray diffraction (XRD) to understand the complex mechanical behaviors of sulfur cathodes, which include both sulfur particles, binders, carbon additives and pores.…”

Chemomechanics is an old subject, yet its importance has been revived in rechargeable batteries where the mechanical energy and damage associated with redox reactions can significantly affect both the thermodynamics and rates of key electrochemical processes. Thanks to the push for clean energy and advances in characterization capabilities, significant research efforts in the last two decades have brought about a leap forward in understanding the intricate chemomechanical interactions regulating battery performance. Going forward, it is necessary to consolidate scattered ideas in the literature into a structured framework for future efforts across multidisciplinary fields. This review sets out to distill and structure what the authors consider to be significant recent developments on the study of chemomechanics of rechargeable batteries in a concise and accessible format to the audiences of different backgrounds in electrochemistry, materials, and mechanics. Importantly, we review the significance of chemomechanics in the context of battery performance, as well as its mechanistic understanding by combining electrochemical, materials, and mechanical perspectives. We discuss the coupling between the elements of electrochemistry and mechanics, key experimental and modeling tools from the small to large scales, and design considerations. Lastly, we provide our perspective on ongoing challenges and opportunities ranging from quantifying mechanical degradation in batteries to manufacturing battery materials and developing cyclic protocols to improve the mechanical resilience.
