Abstract

The invention provides a button cell and a manufacturing method thereof and electronic equipment, and relates to the technical field of batteries. The technical problems that a button cell is poor insealing effect, high in assembly difficulty and low in production efficiency are solved. The button cell is covered on the through hole of the top cover through a conductive piece; the top cover and the conductive piece are connected together in an insulating and sealing manner througha sealing rubber ring; the battery cell is placed in the accommodating cavity of the bottom shell; the first tab on the battery cell is welded with the inner bottom wall of the bottom shell; then the top cover with the conductive piece is connected with the bottom shell in a sealed mode, the second tab on the battery cell is electrically connected with the conductive piece, finally, electrolyte is injected into the containing cavity from the electrolyte injection port in the conductive piece, after electrolyte injection is completed, the electrolyte injection port is covered with the sealing part in a sealed mode, and the sealing part is connected with the electrolyte injection port in a sealed mode. Thebutton cell provided by the invention is used for improving the sealing performance.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a button battery, a manufacturing method thereof, and electronic equipment. Background technique [0002] A button battery refers to a battery that looks like a button in size, generally speaking, it has a larger diameter and a thinner thickness. Because of its small size, the button battery has been widely used in various miniature electronic devices, such as the field of wearable electronic devices and the field of medical products. [0003] Since the inside of the button battery is a closed space, sealing is extremely important for the button battery. However, the prior art button cells are poorly sealed. Contents of the invention [0004] In view of the above problems, embodiments of the present invention provide a button battery, a manufacturing method thereof, and an electronic device for improving sealing performance. [0005] In order to achieve the above purpose, ...
