锂离子电池的原位应力应变检测：光学、声学和电学技术综述

锂离子电池（LIBs）已成为储能的关键设备，推动了全球交通运输和便携式电子产品向电气化的转变。然而，不断追求更高能量密度的锂离子电池从根本上受到化学机械降解的挑战，在化学机械降解过程中，电极在循环过程中发生体积变化，从而产生内应力并限制电池寿命。虽然这些化学力学现象的重要性得到了广泛的认识，但对应力和应变检测的原位检测技术的不同景观进行系统分类的全面审查显然是缺乏的。在这里，我们通过引入一个框架来解决这一差距，该框架根据这些技术的物理形态：光学、声学和电气来组织这些技术。在此框架下，我们批判性地评估了关键方法，包括光激光束位置检测和多光束光应力传感器，声超声波和声发射，电阻应变仪和原位膨胀仪。对于每种方法，我们详细介绍了其工作原理，比较了其优点，并展示了为提高电池性能提供见解的关键研究应用。最后，我们概述了锂离子电池原位应力应变检测的主要挑战和未来方向。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
