Abstract: An electrode assembly including a negative electrode including a sliding region, wherein a first negative electrode thickness ratio of the thickness TN1 of the negative electrode mixture layer at the first face-to-face position where the negative electrode faces the lower end part of the positive electrode, to the thickness TNC of the negative electrode mixture layer at the center part of the negative electrode, and a first positive electrode thickness ratio of the thickness TP1 of the positive electrode mixture layer at the lower end part of the positive electrode, to the thickness TPC of the positive electrode mixture layer at the center part of the positive electrode satisfy the disclosed Condition 1 below. When the disclosed Condition 1 is satisfied, the risk of local NP ratio reversal in the sliding region can be effectively prevented.

Abstract: The present application can provide an electrode, a method of manufacturing an electrode, and a use of the electrode. The present application can provide an electrode without forming the fat edge portion while an insulating layer formed by overlapping with the electrode active material layer on the current collector layer of the electrode effectively secures the insulation required for the electrode. In addition, even when the electrode design model is changed, the present application can provide a manufacturing method capable of manufacturing the above-described electrode by flexibly responding to the relevant change. In addition, the present application can provide a use of the electrode.

Abstract: The present technology relates to a method of managing a sliding region of an electrode, and the method includes: determining a specific region where a positive electrode and a negative electrode, which are subjects of management to be used in manufacturing an electrode assembly, face each other and setting a measurement location in the specific region; measuring a thickness and a loading amount of each electrode mixture layer of the positive electrode and the negative electrode at the set measurement location; measuring a thickness and a loading amount of an electrode mixture layer at each central portion of the positive electrode and the negative electrode; and calculating a ratio of the thickness of the electrode mixture layer of the positive electrode and the negative electrode to the thickness of the central portion.

Abstract: The present invention relates to an apparatus for cleaning press rolls for electrodes, comprising two or more cleaning units provided with cleaning members having grains. According to the present invention, the apparatus for cleaning press rolls for electrodes comprises a plurality of, i.e., two or more, cleaning units, wherein the cleaning units respectively comprise cleaning members having grains with different directions, thus allowing a residual cleaning solution and contaminants to be effectively removed. In addition, when press rolls are cleaned using the apparatus for cleaning press rolls according to the present invention, an aqueous cleaning solution and an alcoholic cleaning solution, which have different properties, can be used together, and after cleaning, the cleaning solutions do not remain on the press rolls, and thus subsequently, secondary contamination of electrodes is prevented, and accordingly, when electrodes are manufactured, the occurrence of defects in the electrodes can be reduced.
