The invention discloses a tab die cutting method and device, a storage medium and a computer program product. The method comprises the following steps: acquiring the thickness of a pole piece between two adjacent pre-die-cut tabs in a plurality of pre-die-cut tabs; according to the thickness of the pole piece between every two adjacent pre-die-cutting tabs, target arrangement positions of the multiple pre-die-cutting tabs in the length direction of the pole piece are determined; according to the target arrangement position, die-cutting the pole piece to form a plurality of tabs; wherein under the condition that the nth pre-die-cut tab is the first pre-die-cut tab, the pole piece thickness between the first pre-die-cut tab and the first end of the pole piece is obtained; the arrangement position of the first pre-die-cut tab on the pole piece is adjusted according to the thickness of the pole piece, the target arrangement position of the nth pre-die-cut tab is obtained, n is a positive integer, and the first end is the end, close to the first pre-die-cut tab, in the length direction of the pole piece. According to the method provided by the invention, the risk of tab dislocation can be reduced, and the production efficiency and the yield of the battery cell are improved.
