Problems solved by technology
Damage phenomena such as leaking ceramics, breakage, and deformation of the separator will lead to a short circuit between the positive and negative electrodes during the winding or lamination process, which will directly lead to the failure of the prepared cells.
However, in the prior art, there is no effective detection device for the diaphragm to immediately eliminate the unqualified batteries prepared by the damaged diaphragm, so the unqualified batteries are still followed by the follow-up process until the finished battery is tested. Unqualified, which greatly wastes subsequent resources and reduces the production yield

The invention discloses a cell core preparation system with pole piece and diaphragm detection. The system comprises a pole piece area, a diaphragm area, a pole piece forming module, a lamination module and a follow-up process. The pole piece forming module, the lamination module and the follow-up process are arranged in turn. The system further comprises a pole piece detecting module for detecting quality of the pole piece area, a diaphragm detecting module for detecting the quality of the diaphragm, a control module for controlling and processing the defective pole piece area or diaphragm area, a first waste box and a second waste box. The invention further discloses a cell core preparation method with the pole piece and diaphragm detection. The cell core preparation system and the method with the pole piece and diaphragm detection of the invention save the resources and improve quality of the product.
Description
【Technical Field】 [0001] The invention relates to the field of preparation of battery cells, in particular to a battery cell preparation system and method with pole piece and diaphragm detection. 【Background technique】 [0002] Lithium batteries are widely used in portable electronic products, electric vehicles, large power sources, secondary charging and energy storage due to their advantages of zero pollution, zero emission, high energy density, small size and long cycle life. The main body of the development and application of power batteries at home and abroad, so the quality of lithium batteries is particularly important. [0003] The electrode pole piece is the main body of the lithium battery, and the quality of the coated pole piece directly determines the quality of the lithium ion battery. Surface defects such as creases, omissions, damage, particles, etc. of the pole pieces will cause quality problems such as short storage time, high self-discharge, and short cycle life...
