Apparatus and method for measuring deformation stiffness of a secondary battery
An apparatus for measuring a deformation stiffness of an article includes a force measuring means configured to measure a force generated in a thickness direction of the article; a thickness measuring means configured to measure a thickness of the article; and a data processor configured to differentiate force with respect to thickness to calculate the deformation stiffness of the article, wherein each of the force and the thickness are a result of a volume change of the article.
