The present invention is a method for manufacturing a secondary battery. An electrode assembly and an electrolyte are accommodated into a body of a battery case. The body of the battery case has an accommodation part and a gas pocket part, and a passage that extends from the accommodation part to the outside discharges an internal gas from the accommodation part through the gas pocket part. The battery case is seated in a seating step on a support block, which has an inclined part on a side surface thereof, to support the battery case. The body is pressed to discharge a gas accommodated in the accommodation part through the gas pocket part in the battery case. This method allows easy discharging of internal gas while reducing discharge of the electrolyte with the gas.

An electrode includes a unit body stack part formed by stacking at least one basic unit having a four-layer structure in which a first electrode, a first separator, a second electrode and a second separator are sequentially stacked. Each surface of the first separator and the second separator is coated with a coating material having adhesiveness, and the basic unit adheres to an adjacent radial unit in the unit body stack part. The electrode assembly of allows a heating and pressing process to be performed prior to a primary formation process so that a separator of one basic unit and a first electrode of the other basic unit to be adhered and fixed by a coating material coated on the separator, and thus a bending phenomenon caused by a difference in electrode expansion rates in a charging/discharging process is prevented.

Stack type electrode assembly in which bending phenomenon is alleviated, and manufacturing method therefor

A charging-discharging device for secondary battery and a secondary battery activation process device are provided. The charging-discharging device of the present invention includes a box-type body including two open parts formed at lateral surfaces thereof; charging-discharging terminals disposed on lateral surfaces of the body; a nonflammable blocking means for opening or closing the open parts at the lateral surfaces; an air conditioning line connected to the inside of the body to individually control the temperature of each charging-discharging device; and/or a CO 2 supply line for spraying carbon dioxide inside the body when a fire occurs. It is possible to uniformly control and manage the internal temperature of the charging-discharging device for performing an activation process of a secondary battery, and when a fire occurs, the fire can be immediately and efficiently extinguished and prevented from spreading to the outside.

Secondary battery charging-discharging device and secondary battery activation process device comprising same
