电池化学必须多样化，以通过有效利用可再生能源来实现可持续的能源景观。碱金属离子、全固态、金属空气电池和多价电池提供独特的成本、安全性、原材料丰富度、能量和功率密度解决方案。然而，实现这些“超越锂离子电池”必须揭示其工作原理和性能与性能关系。在这方面，减轻电极的结构和表面中的化学机械不稳定性在其性能中起着至关重要的作用。不幸的是，由于缺乏操作表征，电化学和机械相互作用之间的耦合往往知之甚少。这篇综述文章解释了曲率测量和数字图像相关测量电池材料应力和应变产生的工作原理。我们提供了这些操作力学测量如何揭示碱金属离子电极，固体电解质，Li-O2电池和水性锌离子电池的不稳定性的具体例子。操作力学测量提供了一种有效的方法来绘制电池材料物理指纹的变化，因此提供了阐明电池材料不稳定性的关键信息。
Battery chemistry must be diversified to achieve a sustainable energy landscape by effectively utilizing renewable energy sources. Alkali metal-ion, all-solid-state, metal–air batteries, and multivalent batteries offer unique cost, safety, raw material abundance, energy, and power density solutions. However, realizing these “beyond Li-ion batteries” must uncover their working principles and performance & property relationships. In this aspect, mitigating chemo-mechanical instabilities in the structure and surface of the electrodes plays a crucial role in their performance. Unfortunately, the coupling between electrochemical and mechanical interactions is often poorly understood due to a lack of operando characterization. This review article explains the working principles of curvature measurement and digital image correlation for measuring stress and strain generations in battery materials. We provided specific examples of how these operando mechanical measurements shed light on instabilities in alkali metal ion electrodes, solid electrolytes, Li-O2batteries, and aqueous Zn-ion batteries. Operando mechanical measurements offer an effective way to map changes in the physical fingerprint of the battery materials, therefore providing crucial information to elucidate instabilities in battery materials.
