Abstract
A battery cell strength testing jig includes a lead gripper in which an electrode lead drawn out from a side portion of a battery cell is fixed. The battery cell strength testing jig further includes a cell fixing member in which the battery cell is fixed. The cell fixing member is installed to be movable in a thickness direction of the battery cell. A relative displacement occurs between a cell body portion and the electrode lead of the battery cell when the cell fixing member is moved.
Claims19
A battery cell strength testing jig comprising:
- a base;
- a lead gripper in which an electrode lead drawn out from a side portion of a battery cell is fixed, the lead gripper coupled to the base;
- and
- a cell fixing member in which the battery cell is fixed, the cell fixing member being installed to be movable linearly in a thickness direction of the battery cell away from the base,
- wherein a relative displacement occurs between a cell body portion and the electrode lead of the battery cell when the cell fixing member is linearly moved.

A battery cell strength testing apparatus, comprises:
- a base;
- a lead gripper in which an electrode lead drawn out from a side portion of a battery cell is fixed, the lead gripper coupled to the base;
- a cell fixing member in which the battery cell is fixed, the cell fixing member being installed to be movable linearly in a thickness direction of the battery cell away from the base;
- and
- a tensile strength tester coupled to an upper portion of the cell fixing member;
- wherein the tensile strength tester relatively displaces a cell body portion with respect to the electrode lead to apply a load to the cell body portion of the battery cell when the cell fixing member is moved linearly in the thickness direction of the battery cell.
