Abstract

The invention belongs to the technical field of soft package batteries, and relates to a packaging method of a soft package button battery, which comprises the following steps: acquiring a pole core with a positive tab and a negative tab; obtaining a first half shell with a first sealing edge and a second half shell with a second sealing edge, which are formed by stamping the flexible packaging film; a first angle is formed between the first sealing edge and the side wall of the first half shell, and a second angle is formed between the second sealing edge and the second half shell; the first angle and the second angle are complementary, and the first angle and the second angle are not right angles; putting the pole core into the first half shell; the first sealing edge and the second sealing edge are in butt joint, so that the first half shell and the second half shell form a shell for accommodating the pole core; performing heat sealing on the first sealing edge and the second sealing edge to form a heat sealing edge; embossing is conducted on the heat sealing edge; and locking the embossed heat sealing edge to form a skirt edge surrounding the periphery of the shell. According to the packaging method, the heat sealing edge cannot be pulled, and the internal structure of the pole core cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of soft pack batteries, in particular to a packaging method for soft pack button batteries. Background technique [0002] Button battery, also known as button battery, refers to a battery that looks like a small button. Generally speaking, the diameter is larger and the thickness is thinner; button batteries are widely used in various microelectronic products because of their small size. application. In recent years, with the development of science and technology, button batteries have become more and more popular in people's lives, which puts forward higher and higher requirements for the safety performance of button batteries. [0003] Especially the soft-packed button battery, which has the advantages of good safety performance (unlike steel-cased and aluminum-cased cells that will explode), light weight, and the like. [0004] When packaging the existing soft-packed button batteries, it is necessary to...
