背景技术Background technique
叠片型电芯是用隔膜将正极极片与负极极片进行隔离叠加而成的,目前,现有叠片型电芯叠片大多通过隔膜“Z”字形叠片将电池极片放置在隔离膜上,180度折弯后再放入另一极片,或者采用简单堆叠式,即将正极极片、负极极片和隔离膜分别裁切为预定大小,然后按照负极极片--隔离膜--正极极片--隔离膜--负极极片的顺序裁切后的正极极片、负极极片和隔离膜进行堆叠,从而得到叠片型电芯,但是,上述两种方式叠片速度较慢,且极片容易发生偏位,导致叠片精度低。The laminated battery cell is made by separating and superimposing the positive pole piece and the negative pole piece with a separator. At present, most of the existing laminated cell stacks use the zigzag-shaped separator to place the battery pole pieces in isolation. On the membrane, bend it at 180 degrees before placing another pole piece, or use a simple stacking type, that is, cut the positive pole piece, the negative pole piece and the separator to a predetermined size, and then follow the negative pole piece-the separator- -Positive pole piece--separation film--negative pole piece sequence The cut positive pole piece, negative pole piece and separator are stacked to obtain a laminated battery cell. However, the lamination speed of the above two methods is higher Slow, and the pole pieces are prone to deviation, resulting in low lamination accuracy.
