Abstract

This application relates to the field of secondary battery production, and in particular to a tab connection assembly and a secondary battery. The tab connection assembly includes a pin and a clamping piece, and the pin includes a connection part and two conductive parts. The two conductive parts are set On both sides of the connecting part, and connected to the connecting part, there are bonding areas on the opposite sides of the two conductive parts. When the bonding area and the side of the tab are attached, the conductive part tends to shrink toward the tab. The clamping part includes a fixed part and two clamping parts, and the two clamping parts are arranged on the side of the fixed part Both sides are connected to the fixed part. The ends of the two conductive parts away from the connecting part can be inserted between the two clamping parts and clamped by the two clamping parts. The clamping part has a contraction toward the conductive part. trend. The structure of the application is simple and reliable, and the thickness of the pins is not limited.

Description

technical field [0001] The present application relates to the technical field of secondary battery production, in particular to a tab connection assembly and a secondary battery. Background technique [0002] At present, secondary batteries have been widely used in portable electronic devices such as mobile phones, digital cameras, and laptops due to their advantages such as high energy density, high power density, high cycle times, and long storage time. Electric vehicles such as electric bicycles and large and medium-sized electric equipment such as energy storage facilities have broad application prospects. This application of lithium-ion batteries has contributed to solving the energy crisis and environmental pollution. [0003] With the improvement of electric vehicle technology, electric vehicles and hybrid vehicles are getting closer to people's daily life. At the same time, electric vehicles have put forward higher requirements for the safety performance of lithium-i...
