US 2025/0242579 A1 · Cell Slitting Method and Slitting Device

Abstract

The present application discloses a cell slitting method and a slitting device. The cell slitting method includes: controlling a pressing plate to tightly press a lamination unit on a cell support table, and controlling the slitting device to slit multiple layers of membranes of the lamination unit according to a pre-set slitting line to obtain m×n independent cell bodies. With respect to the existing slitting device using the mode of cutting off a single cell single-layer tail membrane, according to the present application, the slitting device slits the lamination unit according to a pre-set slitting line such that m×n independent cell bodies can be obtained by simultaneously cutting off multiple layers of membranes, which greatly improves the slitting efficiency and improves the production efficiency of cells.
