Lithium ion battery (air/immersion inspection)

We introduce the cases of air propagation ultrasonic inspection and immersion ultrasonic inspection of inside of a lithium ion battery with NAUT21-I.

In common ultrasonic inspection, we use the couplant such as water and gel.
Air propagation ultrasonic inspection is effective when we inspect the products that dislikes water such as a battery, because this inspection doesn’t need to touch an object or make an object wet.
Air propagation ultrasonic inspection is possible to visualize the inside of a lithium ion battery as plane image.

It requires to specify locations of abnormality in a situation such as research and development of a lithium ion battery. Immersion ultrasonic inspection is possible to visualize information of depth direction inside of a lithium ion battery, and you can check it.

You can watch that we conduct air propagation ultrasonic inspection and immersion ultrasonic inspection of simulation defects inside of a lithium ion battery with NAUT21-I on the movie.
