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.
全球生产格局显示出对高效清洁能源的巨大需求。加强和推进储能系统是优化能源利用和降低成本的关键途径。锂电池是目前最有效且令人印象深刻的能源利用系统,具有安全性好、能量密度高、循环性能优异等优点,占据了大部分市场。然而,由于电池本身电极材料存在缺陷,电极在电化学循环过程中会经历膨胀、应力演变和电极损伤等过程,这会使电池性能下降。因此,检测电化学循环过程中电极的性能变化,如应力演变和模量变化,对于防止锂离子电池性能退化是有用的。本综述介绍了应用于电池电极性能检测的测量系统的当前概况,包括多光束光学应力传感器(MOSS)测量系统、数字图像相关(DIC)测量系统和弯曲曲率测量系统(BCMS),旨在突出不同系统的测量原理和优势,总结使用每个系统的部分研究方法,并讨论提高电池性能的有效方法。
