X-ray detection of devices with higher battery efficiency

Driven by the "going overseas" of lithium-ion battery companies, overseas orders from lithium-ion battery equipment manufacturers have skyrocketed. In the second half of the year, there has been a significant increase in our newly signed orders, especially for overseas orders. "- From a supplier engaged in lithium battery intelligent testing equipment.

The demand for lithium battery equipment in the future will be several times higher than the current demand, so the expansion of lithium battery production is also inevitable. Subsequently, stricter testing process requirements have emerged.

Generally speaking, lithium battery equipment corresponds to each production process of lithium batteries one by one. For example, the equipment involved in the front-end process of the corresponding battery cell (electrode fabrication) includes vacuum mixer, coating machine, roller press, etc; The equipment corresponding to the middle section process of the battery cell (battery cell production) includes winding machines, laminating machines, welding machines, etc; The equipment corresponding to the post cell process (formation and capacitance separation) includes lithium-ion battery charging and discharging motors (used for formation), testing, etc.

The testing requirements required for various production processes are also diverse, usually for lamination, winding, welding, etc., which are detected through X-ray testing equipment with perspective function.

The quality issues of the electrode plates inside the lithium battery may cause low output voltage, abnormal charging and discharging, heating, ignition, and other issues. At present, non-destructive X-ray inspection of lithium batteries is an important method to prevent such problems, especially in the field of electric vehicles, where each electric vehicle is equipped with thousands of cylindrical lithium batteries. In order to ensure the safety of the vehicle, non-destructive X-ray inspection has become a very important detection method.

X-ray testing equipment can detect the solder joints between power battery modules to ensure the stability of their connection. It can also detect the welding quality of the battery's middle ear, as well as the alignment of the positive and negative electrodes and laminations of the battery cell. The testing requirements vary for different parts of the power battery module, so equipment selection and configuration need to be based on actual production and recycling situations.
