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

摘要

Provided is a jig assembly for measuring the tensile strength of an electrode at a bend having a similar radius to a core, an apparatus for measuring bending tensile strength including the jig assembly, and a method for measuring bending tensile strength that measures the tensile strength of an electrode at a bend having a similar radius to a core using the apparatus for measuring bending tensile strength. The jig assembly of the present disclosure includes a fixing unit which fixes one end part of a sample, and a bending jig of plate shape which causes one point bend to a lengthwise direction cross section of the sample having one fixed end part and guides the other end part of the sample toward a tensile testing load unit. According to the present disclosure, it is possible to measure the tensile strength of the electrode under a similar condition to a winding process before the electrode is used in real winding applications.
