ELECTRODE ASSEMBLY FOR EVALUATING PERFORMANCE OF ELECTRODE AND METHOD FOR EVALUATING PERFORMING ELECTRODE

A method and electrode assembly for evaluating performance of an electrode uses a negative electrode on which a negative electrode active material is applied to both surfaces of a negative electrode collector; a positive electrode on which a positive electrode active material is applied to both surfaces of a positive electrode collector and which is stacked with the negative electrode; two separators stacked between the negative electrode and the positive electrode; a reference electrode stacked between the two separators; and a second negative electrode stacked between the separator, which is relatively close to the negative electrode, of the two separators and the negative electrode.
