UBSC-LD50 Ultrasonic Scanning System for Non-Destructive Testing of Pouch and Prismatic Cells
The UBSC-LD50 ultrasonic scanning system is engineered to support detailed non-destructive testing (NDT) of lithium-ion pouch and prismatic cells. It enables researchers and quality control engineers to assess critical internal conditions such as electrolyte diffusion, early-stage gas formation, sealing performance, and lithium plating without damaging the cells. This capability is essential for battery development, failure analysis, and lifecycle prediction.
The system employs ultrasonic C scanning technology using both transmission and reflection wave modes to generate high-resolution images of the internal cell structure. It accommodates cells up to 600 mm in length, 300 mm in width, and 70 mm in thickness. The scanning resolution ranges from 0.5 mm to 30 mm depending on cell thickness, with scan times varying between approximately 1 to 10 minutes per cell. The device operates safely at low ultrasonic power (<100 mW) and supports testing temperatures from room temperature up to 80 °C ± 0.5 °C.
Key Features
- Non-destructive detection of electrolyte distribution and diffusion status within pouch and prismatic cells.
- Identification of early-stage gassing and lithium plating phenomena to aid in cell health monitoring.
- Leak detection and sealing performance evaluation for quality assurance.
- Ultrasonic C scanning with transmission and reflection imaging modes for comprehensive internal analysis.
- XY axis translational scanning stage for precise and repeatable positioning.
- Temperature-controlled oil bath tank with silicone oil coupling medium to ensure consistent ultrasonic coupling.
- Integrated software for motion control, ultrasonic parameter adjustment, and real-time imaging display.
