Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention discloses a heat sealing mould structure for a soft packed lithium electrical core pole ear, wherein the heat sealing mould structure comprises an upper heat sealing mould and a lower heat sealing mould. The upper heat sealing mould has an upper heat sealing head, and one end of the upper heat sealing head forms an upper end single side chamfering structure; a lower heat sealing mould has a lower heat sealing head, and one end of the lower heat sealing head forms a lower end single side chamfering structure; the upper end single side chamfering structure and the lower end singleside chamfering structure are arranged symmetrically along the horizontal plane; the upper end single side chamfering structure has an upper end effective heat sealing end face, and the lower end single side chamfering structure has a lower end effective heat sealing end face; the width of the upper end effective heat sealing end face is equal to that of the lower end effective heat sealing end face. The heat sealing mould structure for the soft packed lithium electrical core pole ear prevents a heat sealing mould from being easily deformed in a machining process, a thermal conduction effect in the pole ear edge heat sealing process is improved, a packing film sol at an electrical core pole ear is guaranteed to meet requirements, and a liquid leakage phenomenon caused by severe heat deformation of the heat sealing mould is prevented from happening in the production process.

Description

technical field [0001] The invention relates to the technical field of heat sealing tabs of soft-packed lithium batteries, in particular to a heat-sealing mold structure for tabs of soft-packed lithium batteries. Background technique [0002] At present, the market’s requirement for soft-pack lithium batteries is that the overall size is the same. Under the same conditions of other performance, the larger the capacity of lithium batteries, the greater the competitiveness, which means that the effective tab heat-sealed side width is smaller, which becomes the lithium battery. It is a difficult problem that core enterprise technicians need to break through. [0003] The effective lug heat-sealing edge width of soft-packed lithium batteries has changed from 2.5mm in the past to 1.5mm now, and then to 1.2mm, which is breaking through recently. By gradually reducing the effective lug heat-sealing edge width, the capacity of lithium batteries is gradually increased. [0004] like...
