BATTERY CELL OF IRREGULAR STRUCTURE CAPABLE OF EFFICIENTLY ACCOMPLISHING ELECTRICAL CONNECTION THROUGH ELECTRODE LEAD

摘要

The present invention relates to a battery cell where an electrode assembly where an anode, a cathode, and a separator interposed between the anode and the cathode are formed is in the battery case of a laminate sheet including a resin layer and a metal layer. The battery cell has an irregular structure where at least five outer sides are formed with a plane. The anode lead and the cathode lead of the battery cell protrude from other outer sides from the outside of the battery case. So, the contact or interference of the leads due to an external force can be prevented.
