Document Type and Number:

WIPO Patent Application WO/2020/114524

Kind Code:

A1

Abstract:

A battery comprising a soft packaged cell (1), comprising the soft packaged cell (1), an electromagnetic shielding piece (2) and a lower cover (3); the soft packaged cell (1) comprises a soft packaged cell body (11), a first tab (12) and a second tab (13), the first tab (12) and the second tab (13) being located on the periphery of the soft packaged cell body (11), and free ends of the first tab (12) and the second tab (13) extending outward; the electromagnetic shielding piece (2) is adhered to the upper surface of the soft packaged cell body (11), the first tab (12) and the second tab (13) are both bent and extend to a position above the upper surface of the electromagnetic shielding piece (2), the bottom of the soft packaged cell body (11) is adhered to the bottom surface of the inner side of the lower cover (3), and the electromagnetic shielding piece (2) and the lower cover (3) are both sealed and filled with injection molding adhesive layers (4). The battery comprising the soft packaged cell (1) reduces the generated electromagnetic interference signal, reduces the generated electromagnetic interference on a product using the battery, improves the quality of the product and the user experience; and avoid the risk of leakage of electrolyte, so as to reduce hidden dangers such as short circuiting of the battery.
