Document Type and Number:
WIPO Patent Application WO/2022/037521
Kind Code:
A1
Abstract:
Provided in the present application are a button battery, a battery module and an electronic device. The button battery comprises a housing, a battery cell, a first pin and a second pin, wherein the battery cell is accommodated inside the housing, the first pin and the second pin are located outside the housing, one of the first pin and the second pin is electrically connected to a positive electrode of the battery cell, the other one of the first pin and the second pin is electrically connected to a negative electrode of the battery cell, and at least one of the first pin and the second pin and the housing are of an integrally formed structure. In the button battery provided in the present application, by means of providing a structure in which at least one of the first pin and the second pin and the housing are integrally formed, instead of using a welding means to achieve connection between the pin and the housing, the problem of poor power supply or structural damage of the button battery due to pseudo welding, missing welding or over welding is ameliorated.
