The new‑energy vehicle and lithium‑battery industries are placing ever‑higher demands on the precision and efficiency of quality inspection. RAYSOV JingShi’s CT division specializes in the research, development, and manufacturing of industrial CT systems, led by a team of PhDs and master’s degree holders. From micro‑focus to high‑energy accelerator‑based CT, we provide end‑to‑end 3D nondestructive testing solutions that cover the entire lifecycle of new‑energy batteries, from R&D through mass production.

Cell internal structure inspection:

Industrial CT enables nondestructive inspection of the internal structure of lithium batteries, clearly distinguishing the positive and negative electrodes, current collectors, and separator conditions, accurately measuring the electrode‑to‑electrode gap, and assessing winding alignment. Compared with conventional two‑dimensional DR imaging, CT provides a clear and precise visualization of the internal structural relationships within the test specimen, furnishing critical baseline data for optimizing cell manufacturing processes.

Electrode and Winding Defect Detection:

Accurately detects electrode‑sheet wrinkles, winding irregularities, misalignment, ear‑welding defects, and internal short‑circuit risks. The RAYSOV Jingshi CT system offers analytical modules such as defect measurement and porosity analysis, helping manufacturers identify root causes at an early stage.

Metallic Foreign Object and Particle Detection:

During the manufacturing of power batteries, the ingress of metallic particles can create a risk of micro‑short circuits. CT systems can automatically detect and localize foreign‑material particles, thereby ensuring battery safety.

Module and PACK Testing:

Inspect the battery module busbar weld quality, busbar connection reliability, adhesive coating uniformity, and insulation layer integrity.

In-situ charge–discharge analysis:

After connecting the charge–discharge apparatus, CT scanning can be performed during charging and discharging, enabling in-situ observation of electrode deformation and internal structural changes within the battery, thereby providing critical data for lifetime assessment and aging‑mechanism studies.

The entire RAYSOV JingShi CT series is equipped with a granite‑based motion architecture, offering excellent resistance to warping and thermal deformation to ensure long‑term, high‑precision, stable operation. It features micrometer‑level repeat positioning accuracy and arcsecond‑level turntable rotational precision, paired with high‑accuracy optical encoders. Powered by our proprietary advanced 3D reconstruction technology, the system supports multiple scanning modes—including continuous scanning, step‑scan, helical scanning, offset scanning, and wide‑field scanning—meeting diverse inspection requirements ranging from button cells to large‑format power battery modules.
