And the positive electrode plates are stacked alternately.

A secondary battery inner cell stack made of such a Z-stacking type is disclosed in Korean Patent Registration No. 10-0313119 and Korean Patent Registration No. 10-1140447.

On the other hand, the secondary battery inner cell stack made of Z-stacking (Z-stacking) is adsorbed one by one each of the negative and positive plates inserted in a stacked form in the magazine unit, aligned in each alignment table. Then, each of the re-aligned negative and positive plates is manufactured by alternately inserting between the separators folded in a zigzag form by a stack table.

However, the negative electrode plate and the positive electrode plate (hereinafter referred to as "electrode plate") inserted into the above-described magazine unit in a stacked form have problems in close contact with each other due to static electricity due to friction and chemicals used in the manufacturing process. When adsorbing the preceding electrode plate, there was a problem that the trailing electrode plate rose along the preceding electrode plate and loaded onto the alignment table.

Thus, the inventor of the present application tried to solve the problem of loading several electrode plates on the alignment table, and as a result, the present invention has been applied for a patent.
