Title:

3D PATTERN CUTTING MACHINE FOR LITHIUM METAL ELECTRODE

Document Type and Number:

WIPO Patent Application WO/2019/013477

Kind Code:

A2

Abstract:

The present invention relates to a 3D pattern cutting machine for a lithium metal electrode and, more specifically, to a 3D pattern cutting machine comprising: a cutting mold punch having a mold suitable for the size of a unit electrode and moving up and down; a die corresponding to the mold punch; a mold blade positioned the periphery of the mold punch so as to cut a lithium metal electrode into a unit electrode; and a 3D pattern positioned at an inside part of the mold punch which contacts the die and has no blade formed thereon. The use of the 3D pattern cutting machine provided by the present invention in producing a lithium metal unit electrode brings about the effect of saving cost and time required for replacing and cleaning a 3D pattern, always constantly engraving shapes of the 3D pattern, and engraving the 3D pattern at the same time as cutting, thereby improving the productivity of a lithium metal electrode.
