Abstract: Lithium-ion batteries (LIBs) present increasing applications in electrochemical energy storage component due to their comprehensive advantages in energy density, cycle life, energy efficiency and safety, there is still a need for further improvement. A large number of advanced characterization technologies has done great contributions to the development of the basic theory in LIBs. Ultrasound technique, as an advanced means for nondestructive testing (NDT), is widely used with the merits of ultrahigh sensitivity, low cost, easy operation and real-time measurement, which has great application potentiality in the field of LIBs characterization. The current research and application situation of the ultrasound technique are summarized and then the prospect is also discussed.

Key words: ultrasonic testing, lithium-ion battery, battery characterization
