Currently, battery manufacturing processes are not a closed-loop process. The configuration parameters are pre-set, and cannot be changed during manufacturing, and one only knows whether the product is good or not until after the manufacturing process is finished and the product sample is tested offline. This results in a high level of wastage mainly due to the lack of real-time evaluation and feedback system for process configuration optimization. Therefore, there are urgent demands for NDE developments. And ultrasound has demonstrated promising capabilities in determining key performances of a multiplayer electrode sheet, such as porosity and tortuosity.

目前，电池制造过程不是一个闭环过程。配置参数是预先设定好的，在制造过程中不能更改，只有在制造过程结束后，离线测试产品样品后，才能知道产品是否合格。这导致高水平的浪费，主要是由于缺乏实时评估和反馈系统的过程配置优化。因此，对无损检测的发展有着迫切的需求。超声波在确定多层电极片的关键性能（如孔隙率和弯曲度）方面表现出了很有前途的能力。
