Embodiment Construction

[0040] In the manufacturing process of lithium-ion batteries, the quality of raw materials and the control of each process have a great impact on the quality of the final finished battery. Moreover, there are many processes in the manufacturing process of the lithium-ion battery, and adverse problems may occur in the manufacturing of each process. Defective problems may be caused by unqualified raw materials supplied by upstream material suppliers, or unqualified back-end process processing and assembly. At present, the production process of lithium batteries is mainly traced through the battery bar code, and it is difficult to obtain the data information of the raw materials that make up the battery cells and the positive and negative electrodes accurately and quickly. If the quality of the finally manufactured lithium-ion battery is abnormal, analysis by some conventional methods has great limitations. On the one hand, it is difficult to accurately determine whether it is a...
