Embodiment 1

[0042] A battery tab, including a positive tab 1, such as Figure 1-3 As shown, the positive electrode tab 1 is an L-shaped structure, and one side of the L-shaped structure is arc-shaped, and the other side is rectangular. The arc-shaped part of the L-shaped structure is a curved portion 2, and the L-shaped structure The rectangular part of the shape structure is the straight part 3. Due to the arrangement of the arc-shaped part, the position of the battery tab can be adjusted, and the position adjustment range is 360° rotation adjustment.

Embodiment 2

[0044] A battery tab, comprising a negative tab 7 and a positive tab 1, wherein the structure of the positive tab 1 is as follows Figure 1-3 As shown, at the same time, both the negative pole tab 7 and the positive pole tab 1 are L-shaped structures, and one side of the L-shaped structure is arc-shaped, and the other side is rectangular. The arc of the L-shaped structure The L-shaped part is a curved part 2 for connecting with the current collector, and the rectangular part of the L-shaped structure is a straight part 3 . Due to the arrangement of the arc-shaped part, the position of the battery tab can be adjusted, and the position adjustment range is 360° rotation adjustment.

Embodiment 3

[0046] A kind of tab PACK processing method adopting the battery tab in embodiment 2, such as Figure 4-7 shown, including the following steps:

[0047] 1) According to the type of the battery 5 to be processed and the type of the circuit board 4 (which can also be a protective plate), determine the length and the lengths of the negative pole tab 7 and the positive pole tab 1 in the battery tabs (these The installation angle between the negative pole tab 7 and the positive pole tab 1; specifically, the size and position of the negative pole tab 7 and the positive pole tab 1 are determined according to the model of the battery 5 required by the customer, L The length of the arc-shaped part of the shape structure is the radius of the battery 5 plus 1mm, that is, the size L of the welded part with the battery current collector (copper foil) 2 It is the sum of the radius of the battery 5 and 1 mm. For the negative pole tab 7 and the positive pole tab 1, the length L of the weldi...

Abstract

The invention relates to the technical field of tab processing, and specifically discloses a battery tab, a tab PACK processing method, a battery finished product and an electronic product. The battery tab is of an L-shaped structure; one side of the L-shaped structure is arc-shaped, and the other side of the L-shaped structure is rectangular; the arc-shaped part of the L-shaped structure is usedfor being connected with a current collector of the battery; the rectangular part of the L-shaped structure is used for being connected with a circuit board of the battery, the battery tab can be bent, laterally deviated and subjected to multi-angle tab PACK machining, and the problem that the position of a battery cell tab of an existing button battery cannot be accurately aligned with the angleof a bonding pad of the circuit board is solved. According to the tab PACK processing method provided by the embodiment of the invention, the battery tab with the L-shaped structure can be laterally bent, and the position of the battery tab can be changed at multiple angles; the welding jig is suitable for different customer requirements, and can also solve the problems of difficult operation, poor welding reliability and low production efficiency caused by the fact that the tab needs to be laterally bent and moved to the bonding pad when the button cell is welded.

Description

technical field [0001] The invention relates to the technical field of tab processing, in particular to a battery tab, a tab PACK processing method, a battery product, and an electronic product. Background technique [0002] With the continuous development of science and technology, lithium battery (lithium-ion battery), as a battery product, has become one of the most potential energy storage systems due to its advantages such as high specific capacity, high energy density, long cycle life, and high working voltage. , and has been widely used. Among them, the tabs are used as the connecting material of the lithium battery product PACK (packaging). It is a metal conductor that draws the positive and negative electrodes out of the battery cell, and plays a role in connecting the battery with the external circuit. Its quality directly affects Battery performance stability. For example, mobile phone batteries, Bluetooth batteries, notebook batteries, etc. used in daily life a...
