As the core and power source of new energy vehicles, the role of batteries is the most critical. This paper analyzes the application and problems of lithium-ion batteries in the current stage.
Due to the inability to directly measure the internal state of batteries, there are technical challenges in battery state estimation, defect detection, and fault diagnosis. Ultrasonic technology, as a non-invasive diagnostic method, has been widely applied in the inspection of lithium-ion batteries in recent years.
Ultrasonic detection offers several distinct advantages over the aforementioned characterization methods for detecting gas defects in LIBs. Firstly, ultrasonic detection can penetrate the aluminum plastic film of batteries, allowing it to monitor tiny bubbles and defects deep inside the battery in real-time.
Defect detection within LIBs requires advanced methodologies for three-dimensional defect localization, enabling the differentiation of electrodes, separators, and aluminum-plastic films within the battery layers.
A comprehensive overview and analysis of the technical approaches, challenges, and solutions for the application of ultrasonic technology in battery state estimation is provided. The current state, main technical approaches, and challenges of ultrasonic technology in battery defect and fault diagnosis are summarized.
Ultrasonic technology, as a non-invasive detection method, shows great potential in lithium battery manufacturing and management. Fig. 17 summarizes the application scenarios of ultrasonics in LIBs. Firstly, ultrasonic technology has a broad application prospect in the state estimation and fault diagnosis of LIBs.
