WIPO Patent Application WO/2020/159235
Kind Code:
A1
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.
