Abstract
A battery cell pressure jig of an embodiment of the present invention includes a first pressure block and a second pressure block pressurizing both sides of a battery cell with the battery cell interposed therebetween. The first pressure block and the second pressure block each includes: a flat-type pressure plate that presses the battery cell; a support plate supporting the pressure plate; hinge members provided at the upper edges of the pressure plate and the support plate so that the pressure plate and the support plate are mutually foldable; and an elastic member coupled to the lower end of either the pressure plate or the support plate. The battery cell pressure jig may sequentially press the battery cell from the lower portion to the upper portion.
Claims13
A battery cell pressure jig, comprising:
- a first pressure block and a second pressure block configured to apply pressure to both sides of a battery cell when the battery cell is interposed between the first and the second pressure block, and
- wherein the first pressure block and the second pressure block each comprise:
- a pressure plate oriented so as to face the battery cell and being configured to press the battery cell, wherein the pressure plate is a flat-type pressure plate;
- a support plate supporting the pressure plate;
- hinge members joining the pressure plate and the support plate, so that the pressure plate and the support plate are mutually foldable;
- and
- an elastic member coupled to the pressure plate or the support plate, so as to be compressed when the battery cell is pressed.
