Title:
BUTTON CELL AND POWER CONSUMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/183492
Kind Code:
A1
Abstract:
A button cell (1) and a power consuming device, relating to the technical field of batteries. The button cell (1) comprises a housing assembly (100), an electrode assembly (200), a first electrode tab (300), and a second electrode tab (400). The housing assembly (100) comprises a first electrically conductive portion (110) and a second electrically conductive portion (120), wherein the first electrically conductive portion (110) is insulated from the second electrically conductive portion (120). The electrode assembly (200) comprises first pole pieces (210) and second pole pieces (220) with opposite polarities. The first electrode tab (300) comprises a first connecting portion (310) respectively connected to each of the first pole pieces (210), and a first continuously curved extending portion (320); and one of the first electrically conductive portion (110) and the second electrically conductive portion (120) is connected to the first pole piece (210). When the button cell (1) drops, the electrode assembly (200) inside the housing assembly (100) is displaced relative to the housing assembly (100); and since the first extending portion (320) of the first electrode tab (300) is continuously curved, the first extending portion can be easily deformed under the action of an impact force during the dropping process, and can also absorb some of the energy of the impact force during the process of deformation. Therefore, with the button cell (1), the hidden danger of breakage of the electrode tab when the button cell (1) drops can be effectively reduced.
