A kind of lithium battery production process

Abstract

The invention belongs to the technical field of lithium batteries, and specifically relates to a lithium battery production process. The process uses a slitting machine, the slitting machine includes a workbench and a shearing mechanism, and the shearing mechanism includes a primary cutting unit and a re-cutting unit; The initial cutting unit is set in the middle of the workbench. The initial cutting unit includes the lower support plate, the lower pressing plate and the cutting assembly. The initial cutting unit is used to score the pole plate; On the table; the re-cutting unit includes an upper support plate, an upper pressing plate and a cutting assembly. The re-cutting unit is used to cut off the pole plate. There is a notch at the bottom of the upper pressing plate, and an adjusting unit is arranged in the notch; the adjusting unit includes a left slider, Right slider and lead screw. The invention adopts the method of notching one side of the polar plate first, and then cutting from the other side of the polar plate, so as to reduce the amount of shearing deformation of the polar plate, improve the quality of the polar plate slice, and avoid the winding leakage of the subsequent polar plate, and the positive and negative Pole contact causes an internal short circuit.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, in particular to a lithium battery production process. Background technique [0002] Polymer lithium-ion batteries are very commonly used batteries at present. At present, the research and production of polymer lithium-ion batteries have made significant progress, and their applications in various fields are becoming more and more extensive. In recent years, polymer lithium-ion batteries are the preferred batteries for mobile electronic devices such as mobile phones. [0003] With the widespread use of polymer lithium-ion batteries, there are more and more fields that require polymer lithium-ion batteries, which requires the production of more and more polymer lithium-ion batteries to meet the needs of use. The existing plate slitting process uses a plate shearing machine to cut the plate, but the size of the plate cut out by the current plate shearing machine is very easy to produce a...

Problems solved by technology

[0005] The shearing process of this technical solution can save processing time, improve work efficiency, and reduce the labor intensity of operators; Deformation occurs at the cut-off point, which makes the subsequent winding leakage film, positive and negative contacts cause internal short circuit, so that the application of the shearing process should not be high.
