Disclosed in the present invention are an ultrasonic scanning device, use thereof, and a method, which belong to the field of ultrasonic testing. The ultrasonic scanning device comprises at least one pair of cylindrical rollers, axes of cylindrical rollers in each pair being parallel to each other, liquid for ultrasonic transmission being accommodated in each cylindrical roller. When said device works, a pair of cylindrical rollers rotate around their own axes, the rotation directions being opposite, and an object to be tested passes between the pair of cylindrical rollers, so as to undergo ultrasonic testing. The ultrasonic scanning device can be used in the field of lithium ion battery testing; by means of acquiring an ultrasonic image from inside a tested object, the internal defect and health state of a lithium ion battery can be acquired. Said device in the present invention is simple in structure, easy to use, low in cost and ingenious in design, having a good practical use effect in the field of the li
