Abstract
A secondary battery static pressure jig and a secondary cell internal pressure control method using the same is provided. The secondary battery static pressure jig, includes: a supporting member disposed on both surfaces of a battery cell to support the battery cell; a piezoelectric element that is disposed on at least one of surfaces of the supporting member and the battery cell contacting each other and measures a pressure applied to the battery cell; and a controlling part that controls a volume of the piezoelectric element according to the pressure measured by the piezoelectric element, wherein a volume of the piezoelectric element may be changed according to the volume change of the battery cell, and the pressure applied to the battery cell from the supporting member by the volume change of the piezoelectric element may be made to be a constant pressure.
