Abstract

The invention discloses a welding method of a copper strip, comprising the following steps of step 1: the copper strip to be welded is arranged on a metal part to be welded; step 2: a nickel strip is arranged on the copper strip to be welded; step 3: the nickel strip is spot-welded by spot welding equipment, thus welding the nickel strip and the copper strip with the metal part to be welded together. The invention also discloses a welding method of a copper tab in a lithium battery and the lithium battery which is made by the method. The copper strip can be conveniently welded by adopting the invention, the rickets problems when the copper tab is welded with a pressing plate, and the production cost of the lithium battery is reduced.
