Steel thin tape is perforated by needles. The active material is enclosed in the so-called pockets out of the perforated tape. The individual pockets are mechanically interconnected with one another, so this interconnected pocket is in the form of one plate. Plate tab and plate frame are fixed to this plate by mechanical press, so electrode plate is completed.

Electrode plates are stacked. Post of a battery and related parts are also attached. And separators are inserted into assembled electrode plate group and separator edges are put in order by machine. Electrode plate group is tightened by resin band using binding machine. So electrode plate group is completed.

Plates group is activated by repeat of charging and discharging so as to have rated capacity. Next, the electrode plate group is installed in a container and lid is attached to it. The cell is filled with electrolyte and charged to the rated capacity. So, cell assembled cell group and relative parts are attached to them, and these are shipped.
