The lithium battery industry has maintained rapid development driven by the growth of downstream demand for global consumer electronics, new energy vehicles and energy storage, and the market scale continues to expand. The quality of lithium batteries is not only related to the sales of the manufacturer's own products, but also related to the competitiveness of downstream products, which will ultimately be reflected in the daily life of users and affect the safety of users.
Although lithium batteries are generally very safe, we often see some safety accidents caused by lithium batteries, and the most impressive is the phenomenon of lithium batteries.
Lithium battery has been developed for more than ten years since its birth, and most of the mobile phones on the market are also built into lithium batteries. Excluding incorrect use, external environment and other factors, cell quality problems and pack process problems must be the most concerned by lithium battery manufacturers.
The analysis of the internal structure of lithium batteries is a necessary process to promote process optimization and quality control, and the use of X-ray tomography technology can non-destructively measure the internal structure, which can not only monitor the assembly status, but also help analyze the real cause of lithium battery failure.
The lithium battery is scanned by industrial CT to analyze the internal structure of the lithium battery, such as the arrangement of the electrode layer inside the lithium battery, the spacing between the positive electrode, the separator and the negative electrode, internal defects, short circuits, etc.
