BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/110142
Kind Code:
A1
Abstract:
A battery (100), comprising a housing (1), and a circuit board (3) and a cell module (2) arranged in the housing (1); the cell module (2) comprises a plurality of cells (20), the cells (20) each comprising a cell body (21) and tabs (22) arranged on the cell body (21), the tabs (22) being connected to the circuit board (3), the cell bodies (21) each comprising an end provided with the tabs (22) and an end far away from the tabs (22), the ends of the cell bodies (21) provided with the tabs (22) being adhered to one another, the ends of the cell bodies (21) far away from the tabs (22) being adhered to one another, and the adhesion strength between the ends of the cell bodies (21) provided with the tabs (22) being less than the adhesion strength between the ends of the cell bodies (21) far away from the tabs (22). The present invention further relates to an electric device. By using the described battery (100), when the cells (20) deform, because the adhesion strength of the ends of the cell bodies (21) provided with the tabs (22) and the adhesion strength of the ends of the cell bodies (21) away from the tabs (22) are different, the tabs (22) are disconnected from the cell bodies (21) or the circuit board (3), cutting off the current, avoiding the problem caused by overcharge inside the battery (100), and improving the safety performance of the battery (100).
