Abstract: A method for quantitatively analyzing cohesive failure of an electrode analyzes cohesive failure of an electrode and includes preparing an electrode in which an electrode material mixture layer including an electrode active material, a conductive agent, and a binder is formed on a current collector, measuring shear strength (σ) data according to a cutting depth while cutting the electrode material mixture layer from a surface thereof until reaching the current collector using a surface and interfacial cutting analysis system (SAICAS), obtaining a regression curve of shear strength according to the cutting depth from the shear strength (σ) data, and determining a cutting depth, at which the shear strength is minimum in the regression curve, as a location of cohesive failure.

Abstract: An electrode for a secondary battery including a current collector, and at least one electrode material mixture layer on a surface of the current collector, the electrode material mixture layer including a negative electrode active material, a conductive agent, and a binder wherein, the electrode has a property such that in a regression curve obtained by regression analysis of shear strength data according to a cutting depth which are measured while obliquely cutting the electrode material mixture layer from a surface thereof until reaching the current collector using a surface and interfacial cutting analysis system (SAICAS), a ratio of a maximum value (σmax) to a minimum value (σmin) of shear strength is 1.7 or less.
