Why does the lithium battery separator deform after a few days after being slit?
The reasons for the deformation of the lithium battery separator after slitting are as follows:
(1) The speed and tension of the diaphragm during slitting are two key factors that affect the effect of the diaphragm after slitting. You can try to change the existing process and do a small-scale experiment.(High Speed Slitting Machine)
(2) Control of moisture in the diaphragm. The poor skirt after slitting may be caused by the inhalation of moisture in the diaphragm. You can try to strictly control the moisture in the diaphragm slitting workshop and exhaust the influence of moisture in the air.
Yixinfeng J350D-3 high-speed hardware die-cutting machine, developed after years of technology accumulation, has the following characteristics:
●Advanced design concepts to ensure product safety and reliability;
●Using lightweight carbon fiber rollers, reducing the weight of the rollers from 2.8kg to 0.5kg, providing effective technical support for high-speed die-cutting;
●The die-cutting method with its own intellectual property rights ensures the high efficiency of die-cutting and the dimensional accuracy of the pole piece;
●The mold has a quick change function;
●High-precision molds to ensure die-cutting times and die-cutting quality;
●Mold self-cooling function and air cushion function, effectively improve the service life of the mold;
●Pole piece traction is directly driven by DD motor to reduce the transmission error of the intermediate link, and the dimensional accuracy can be controlled within ±0.2mm;
●Non-contact dust removal, reducing the secondary pollution of dust, and effectively avoiding the damage to the pole piece by brushing powder;
●Individual dust-collecting devices are installed in dust-prone places (tape connection, die-cutting place), which greatly reduces the occurrence of dust pollution;
●The device has a code scanning function, which combines the code scanning information with pole group information (positive and negative plates, pole piece status information, etc.), personnel information, and
Binding of environment information, equipment information, etc., and ensure the consistency of the two-dimensional code with the information of the corresponding pole group, and send it to the MES.
