JIG ASSEMBLY COMPRISING BEND JIG, BEND TENSILE STRENGTH MEASURING DEVICE INCLUDING SAME, AND BEND TENSILE STRENGTH MEASURING METHOD USING SAME

Document Type and Number:

WIPO Patent Application WO/2019/004728

Kind Code:

A1

Abstract:

Provided are a jig assembly for enabling electrode tensile strength to be measured at a bend having a radius similar to that of a core, a bend tensile strength measuring device comprising the jig assembly, and a bend tensile strength measuring method for measuring electrode tensile strength at a bend having a radius similar to that of a core by using the bend tensile strength measuring device. The jig assembly of the present invention comprises: a fixing part for fixing one end of a specimen; and a plate-shaped bend jig for causing a one-point bend on the longitudinal cross-section of the specimen of which one end is fixed and for guiding the other end of the specimen toward the tensile test load part. According to the present invention, electrode tensile strength can be measured under a condition similar to that of a winding process before an electrode is actually wound.
