Abstract

The embodiment of the invention provides a battery cell manufacturing method. The method comprises the steps that a roll core comprising a pole piece is provided, the pole piece comprises an electrode and a tab arranged on one side of the electrode in a protruding mode, and a solder layer is arranged on the surface of the tab; enabling a current collecting plate to abut against the tab; and the collector plate and the tab are inductively welded together through a solder layer. According to the method, no metal slag is generated in the technological process of welding the collector plate and the tab, and the production efficiency is high.
