Stacked cells are new generation batteries having wide-ranging benefits such as increased energy density, reduced internal resistance, and increased discharge ability at high costs. Moreover, they cannot be deformed easily. The invention of these stacked cells has become an anticipated step for further progress in this industry. So the technology of x-ray inspection of batteries is very important in the batteries industry.
The process of stack involves attaining flexible size by rolling the cell. This step is not restricted by the winding pin assembly, production way, and high interface uniformity of the pole piece. It will be extensively used in creating automotive-grade power cells in the future.
Data reveals new findings by comparing the cells with the traditional winding process. The space utilization rate at the edges of stacked cells becomes more. The energy density can be improved by 5%. The duration of the life cycle as well as the reduced distortion and extension during this cycle is improved by more than 10%. These stacked cells have got increased battery safety, simple structure, and improved structural adaptability.
Our instrument is controlled by a programmable logic controller (PLC). It releases X-rays via the X-RAY generator. Next, it passes through the internal structure of the battery. The resultant rays are captured by the imaging system, processed by the related software, and manually estimated. This industrial x ray equipment is used to determine the arrangement of the stacked pieces within the battery and precisely differentiate good products from defective ones. The instrument has a built-in horizontal rotating platform. Hence, it is not essential to fix the battery sideways to prevent the displacement of the pole piece caused due to sideways. It can be placed directly flat and rotated at any angle for inspection. This instrument is quick and convenient to operate while preventing artificial harm to the battery.
This semi-automatic x ray battery inspection equipment helps to assess square stacked batteries. It uses the oblique perspective image of the battery edges to check for misalignment of the pole piece. This equipment has automatic positioning to determine the degree of alignment of the cell’s pole piece. It helps in predicting whether the quality of this battery is proper or not.

|By illuminating the bottom two corners at 45 degrees, you can see the positive and negative electrode packaging, to detect whether the battery quality is okay or not.
2.3 Decision method
A decision is made by comparing the measured value with the standard set interval value. (A decision criterion can be set according to the requirements of the process)
Note: The lower and upper limits of the standard interval are set by customers according to the control ability of their own process.
