Abstract
The invention provides a method for bending two spliced roll core electrode lugs of a flexible-package lithium battery. By the method, bending difficulty and material cost can be lowered. The method includes the following steps: (1) splicing two roll cores; (2), welding flexible-package composite electrode lugs with the roll cores which are spliced, namely using an ultrasonic welder to weld welding portions of two customized flexible-package composite electrode lugs with two reserved electrode lugs respectively; (3), bending the electrode lugs. In the method, a mode of welding and then bending the reserved electrode lugs is adopted, so that easiness in welding, positioning and bending is realized; the electrode lugs after being bent do not protrude, so that convenience is brought to subsequent processing; materials used at ends where the electrode lugs of the roll cores are welded with the flexible-package composite electrode lugs are short, so that material cost is saved; bending is performed directly after welding, and cutting is not needed, so that a process is omitted, and production efficiency is improved and processing cost is lowered.
Description
Technical field
The present invention relates to a kind of lithium ion battery production method, especially a kind of flexible packing lithium ion battery two spells core lug bending method.
Background technology
The mode that current flexible packing lithium ion battery two core splicing, welding, lug bending are taked, substantially be first weld the mode cutting last bending again, splicing two core lug used, Soft Roll compound lug welding ends are reserved long, cause waste of material, this welding manner compound lug welding ends is not easily located front, welding could bend after need cutting out, can not directly bend, and bending difficulty is large, after bending, lug easily protrudes, affect battery outward appearance after encapsulation, puncture aluminum plastic film time serious and cause battery to scrap.
Summary of the invention
The invention provides a kind of flexible packing lithium ion battery two reducing bending difficulty and material cost and spell core lug bending method.
The flexible packing lithium ion battery two realizing the object of the invention spells core lug bending method, comprises the steps:
(1) two core splicing: two of flexible packing lithium ion battery core are closed up alignment, fixes with lithium ion battery special adhesive tape; Two lugs of the first core keep vertically, two of the second core lugs being against battery diaphragm, towards the lug bending 90 ° of the first core, and being close to the lug of the first core; After bending, the lug of the first core and the lug of the second core are combined into reserved lug;
(2) Soft Roll compound lug welds with splicing core: use supersonic welder the weld part of two the Soft Roll compound lugs customized respectively at two reserved tab weldings;
(3) lug bending: postwelding Soft Roll compound lug and reserved lug are together against battery diaphragm to same direction curved 90 °, then the film lower edge 90 ° of Soft Roll compound lug along weld part top and Soft Roll compound lug is turned up; After twice bending, Soft Roll compound lug keeps vertical, finally pastes lithium ion battery special adhesive tape and fixes Soft Roll compound lug.
Described step (3) turns up the film lower edge 1mm gap location 90 ° of Soft Roll compound lug along weld part top and Soft Roll compound lug.
The beneficial effect that flexible packing lithium ion battery two of the present invention spells core lug bending method is as follows:
1, flexible packing lithium ion battery two of the present invention spells core lug bending method, and the mode adopting the reserved lug of first welding to bend again, is easy to welding location, is easy to bending;
2, after bending, lug can not be protruding, for following process is provided convenience;
The lug of 3, two core and the welding ends material of Soft Roll compound lug short, save material cost;
4, directly bend after welding, without the need to cutting, reducing by a procedure, boosting productivity and processing cost.
