A method for manufacturing a prismatic battery is provided to remove thickness difference among battery cells effectively while minimizing damage to a battery cell, to reduce working time and production costs, and to improve a working environment. A method for manufacturing a prismatic battery having an electrode assembly within a prismatic battery case comprises a step of compressing a battery cell in a thickness direction by rollers(110,120) to remove thickness difference among battery cells while transferring the battery cells on a belt conveyor(130,140), wherein the battery cell is injected with an electrolyte and sealed. The battery cell is transferred between a pair of rollers with a predetermined distance to the same direction as a movement direction of the belt conveyor and is compressed in a thickness direction at the same time. |
