Abstract

The invention discloses a preparation method of a copper flexible connecting piece for a new energy automobile battery. The preparation method comprises the following steps: S1, fixing conductive metal sheets on the upper and lower surfaces of a conductive metal foil, welding to form a connecting sheet, and polishing; and S2, bending and forming the connecting piece to enable the connecting piece to form a wavy structure, sleeving the periphery of the connecting piece with a heat-shrinkable sleeve, and passing through a tunnel furnace to obtain the copper flexible connecting piece for the new energy automobile battery, wherein the polishing treatment is performed by using a polishing treatment solution. The copper flexible connecting piece prepared by the preparation method of the copper flexible connecting piece for the new energy automobile battery has good anti-corrosion and anti-oxidation effects, and the anti-corrosion effect can be remarkably improved by polishing the copper flexible connecting piece through the polishing solution.
