Claim 6:
7. A pressurizing short-circuit inspection apparatus, comprising:
compression plates arranged with a predetermined separation distance therebetween so that at least one secondary battery cell is insertable therebetween, the compression plates being movable along a first axis to adjust the separation distance; and
a pressurizing short-circuit inspection assembly having a cell pressing unit configured to be pressable against a predetermined region of a body of the secondary battery cell and a power supply configured to be contactable with an electrode lead of the secondary battery cell to apply a test voltage, the pressurizing short-circuit inspection assembly being mounted to the compression plates to be movable along a second axis perpendicular to the first axis,
wherein the cell pressing unit includes balls provided at at least one surface thereof to be pressable against the body of the secondary battery cell,
wherein the pressurizing short-circuit inspection assembly further includes a structure-reinforcing block unit configured to connect the cell pressing unit and the power supply into a single body, and
wherein the structure-reinforcing block unit includes:
an upper block configured to connect top portions of the cell pressing unit and the power supply and mounted to a top end of each compression plate to be slidable thereon; and
a lower block configured to connect bottom portions of the cell pressing unit and the power supply and mounted to a bottom end of the compression plate to be slidable thereon.
