Embodiment 1
[0048] Embodiment 1: as Figure 1~5 , a battery pole piece coating system, comprising a coating head 4, an oven 3 and a winding device 1; the winding device has 3 independent winding modules;
[0049] Coater head for coating slurry 6 on the foil strip;
[0050] The foil strip is bonded together by N foil sub-bands through adhesive 2; two adjacent foil sub-bands are spread out in the width direction of the foil strip and partially overlap;
[0051] After the foil strip passes through the oven, the glue loses its cohesive force due to heating, and the three pole pieces are separated and wound up by three independent winding modules of the winding device.
[0052] Glue is adhesive tape.
[0053] The 3 foil sub-tapes have the same width.
[0054] A method for coating a battery pole piece, using the aforementioned battery pole piece coating system for coating.
[0055] The coating steps are as follows:
[0056] Step 1; coating slurry;
[0057] Coating the positive and negativ...
