Problems solved by technology

[0005] However, as the battery volume increases, new problems will arise. When the battery volume increases, if the original two-pole assembly battery technology is used, the length of the electrode tab (for example, greater than 25mm) will be too long
If the tabs of the el

Abstract

The invention discloses a quadrupole group assembling structure of a battery. The quadrupole group assembling structure comprises a first pole group pack combination and a second pole group pack combination; the first pole group pack combination comprises a first pole group and a second pole group; a first positive tab on the first pole group and a second positive tab on the second pole group are connected through one end of a positive connecting sheet; a first negative tab on the first pole group is connected with a second negative tab on the second pole group through one end of a negative pole connecting sheet; the second pole group pack combination comprises a third pole group and a fourth pole group; a third positive pole lug on the third pole group is connected with a fourth positive pole lug on the fourth pole group through the other end of the positive pole connecting piece; a third negative pole lug on the third pole group is connected with a fourth negative pole lug on the fourth pole group through the other end of the negative pole connecting piece; and the positive pole connecting piece and the negative pole connecting piece are respectively connected with a positive pole and a negative pole on the battery cover. According to the invention, the length of the tab is not increased in the assembly process while the volume of the battery is increased, and the quality problem caused by the overlong tab is reduced.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a battery quadrupole assembly structure. Background technique [0002] At present, lithium-ion batteries have the advantages of high safety, high efficiency, no pollution, high specific energy, and many cycles. They are widely used in new energy vehicles and energy storage consumer products. At present, the entire battery industry has stricter requirements on the cost and quality of lithium batteries. [0003] Reducing the ratio of battery cost to module cost has become a top priority, specifically by reducing the cost per unit of the battery and reducing the cost of the module assembly process. [0004] Regarding the cost per unit of the battery, it can be achieved by reducing the ratio of the cost of battery structural parts to the cost per unit of the battery. Increasing the volume of the battery can increase the utilization rate of structural parts in the battery, thereby ...
