摘要： This technology relates to a system and method for measuring physical properties of an electrode specimen. According to the present invention, it is possible to suppress a slipping phenomenon of an electrode specimen and prevent disconnection of a gripping portion during a tensile test for the electrode specimen by forming a masking tape on the gripping portion of the electrode specimen and forming a grid pattern on the surface of a pressing jig.
