摘要： The present invention relates to a pouch type case having trimming portions formed on both sides or four corners thereof and a battery pack including the same. The trimming portions are formed on the corners of the pouch type case such that the trimming portions are indented toward an electrode assembly accommodating part to reduce a unit area so as to increase pressure applied to unit cells when a battery pack is assembled, thereby facilitating assembling of the battery pack and increasing cell capacity per unit area. Furthermore, the unit cells can be fixed in the battery pack more stably. The pouch type case reduces the unit area so as to include a relatively large number of cells for pressure applied to the cells when the battery pack is assembled to thereby increase the cell capacity.

摘要： A forming tool and a forming method for producing an overpressure predetermined breaking point in a battery cover by deformation. The forming tool has a stamping tool and a die tool and an optional hold-down arrangement. On the die tool a support surface is provided for the battery cover to be deformed to form a forming cavity in the die tool in a depressed manner. On the stamping tool a stamp part and a ring-shaped stamp part is provided corresponding to a bead to be created in the battery cover in the cross-section. During deformation of the battery cover the stamping tool is pressed in the battery cover, whereby material of the battery cover flows into the forming cavity. Thereby the stamping tool is approached to the forming cavity in a manner such that the remaining distance corresponds to a minimum wall thickness at the overpressure predetermined breaking point.
