Analysis of the cause of lithium battery explosion, X-ray CT protects the safety of lithium batteries

As lithium-ion batteries are widely used in consumer electronics, new energy vehicles, military products, aviation products and other fields, the fire danger gradually emerges. Many influential fire accidents have occurred at home and abroad, and large-scale related products have been triggered. recall. The successive explosions of lithium batteries not only alarmed the industry, but also prompted scientists to conduct more in-depth research on battery failures. A study of the internal structure of lithium batteries with the help of X-ray CT technology was published in "...

X-ray three-dimensional microscope technology and principle

As a new generation of high-resolution detection technology platform, X-ray three-dimensional microscope adopts a dual-detector design scheme (as shown in the figure below), which is a high-efficiency flat-panel detector and a multi-rate photocoupler detector. The user can switch between two sets of optical path systems according to different sample requirements. The flat-panel detector can be used to observe the sample in a wide range, the field of view can reach 130mm, find the characteristic target area, and then use the optical coupler detector to target area
