Automatic Battery Electrode Winding Machine for 4680 Tabless Battery and All Cylindrical Cell

SPECIFICATIONS

Contact us for more information about this automatic battery electrode winding machine, it is suitable for all cylindrical lithium-ion battery electrode preparation, especially for 4680 tabless battery.

This machine is mainly used for winding cylindrical lithium ion battery cells. The working process is as follows: the positive and negative electrodes and the separator are actively unwinding, respectively through tension control, dust removal device and correction device (with pre-roll correction function), the separator has the function of removing static electricity, introduced into the winding part and winding according to the process requirements, stick termination tape. After the finished product is reamed, it is automatically unloaded, after short circuit detection and defective product rejection, the good product is delivered to the collection table to realize the fully automatic winding process.

1)The number of tabs of a single electrode≤2;
2)Two methods of positive first-in or negative first-in can be set freely by modifying parameters.
3)The electrode coating must be uniform, and the length and position should be well controlled. After rolling, the wave is less than 1mm, and the serpentine bend is less than 0.3mm / 1000mm (subject to not affecting the winding accuracy);
4)The electrode must be continuously slitting, the width error is less than ± 0.05mm, the material roll must not have an obvious tower type (not more than ± 1 mm), and the winding tension is uniform;
5)The termination tape must be evenly wound without obvious tower shape, wrinkles, warpage, etc .
