System for measuring physical properties of electrode specimen using masking tape, and method for measuring physical properties using same

A system for measuring a physical property of an electrode specimen, the system comprising:

• an electrode specimen including:
• a coated part region where an electrode mixture layer is on a surface of a metal current collector, a first gripping portion being defined at a first end of the electrode specimen in the coated part region and the first gripping portion having a tape thereon, and
• a non-coated part region at a second end of the electrode specimen where an electrode mixture layer is absent on the surface of the metal current collector, a tape being absent of the second end;
• and
• a tensile strength measuring unit that includes a first gripping unit configured to grip the first gripping portion of the electrode specimen and a second gripping unit configured to grip another end of the electrode specimen, the tensile strength measuring unit being configured to measure tensile strength for the electrode specimen by moving the electrode specimen in a pulling direction along a length direction of the electrode specimen by pulling with at least one of the first and second gripping units,
• wherein each of the first and second gripping units includes a pressing jig having gripping structures facing each other while having the first gripping portion and second gripping portion of the electrode specimen between respective ones of the first and second gripping units, and wherein the pressing jig includes a rubber or metal jaw face,
• wherein the pressing jig of the first gripping unit grips the first gripping portion of the coated part region and includes a metal jaw face where a grid is on a surface of the metal jaw face, and
• wherein the pressing jig of the second gripping unit grips the second gripping portion of the non-coated part region and includes a rubber jaw face.
