Abstract
The present application provides a secondary battery, an apparatus and a manufacturing method for a secondary battery. The electrode assembly is housed in the packaging bag, and the electrode assembly includes a main body portion and a first electrode tab extending from the main body portion. The first electrode tab is set in multiple layers, and the multiple layers of the first electrode tab are connected by ultrasonic welding to form a first welding region. The electrode lead is connected to the electrode assembly and extends to an outside of the packaging bag, and the electrode lead is connected to the multiple layers of the first electrode tab by laser welding to form a second welding region. In a plane perpendicular to a thickness direction of the electrode lead, a projection of the second welding region is located in a projection of the first welding region.
