Problems solved by technology

Among them, the single composite sheet stacking method uses the cylinder to drive the pressing sheet to alternately compress the pole piece. The productivity of this sheet pressing method is low, which seriously affects the production cycle of the entire battery. Folding into batteries, although the productivity has been improved to a certain extent, it still cannot meet the market's demand for lamination efficiency and battery productivity.

Abstract

The invention discloses a composite lamination process, belonging to the technical field of battery cell production. The composite lamination process comprises the following steps: firstly, compounding a first positive plate, a first negative plate and two layers of first diaphragms to prepare a first composite belt, and compounding a second positive plate, a second negative plate and two layers of second diaphragms to prepare a second composite belt; then compounding the first composite belt and the second composite belt to form a four-pole piece composite belt; and then folding the four-pole piece composite belt to form a battery cell. Compared with the prior art, the composite lamination process provided by the invention adopts the step of compounding the first composite belt and the second composite belt to prepare the four-pole piece composite belt, so a plurality of continuous composite pieces can be folded into the battery cell, lamination efficiency is high, and battery cell productivity is high.
