Secondary battery and electric device

Abstract

Disclosed in the present application are a secondary battery (100) and an electric device (1000). The secondary battery (100) comprises a case (10), an electrode assembly (20), a positive terminal (30), a negative terminal (40), and a first bonding member (50). The electrode assembly (20) is accommodated in the case (10) and comprises a first flat portion (201), a first curved portion (202), a second flat portion (203) and a second curved portion (204). The first bonding member (50) comprises a first base layer (51), a first adhesive layer (52) and a second adhesive layer (53), wherein the first base layer (51) comprises a first section, a second section and a third section, the first section being located between the case (10) and the first flat portion (201), the second section being located between the case (10) and the second flat portion (203), and the third section connecting the first section to the second section and surrounding the first curved portion (202); the first adhesive layer (52) bonds the first section to the case (10); and the second adhesive layer (53) bonds the second section to the case (10). In the secondary battery (100), the provision of the first bonding member (50) can improve the drop resistance performance of the secondary battery (100), thereby prolonging the service life thereof.
