BATTERY CELL HAVING STRUCTURE FOR COATING WITH ELECTRICAL INSULATING MATERIAL ON END OF SEALING PART BENDED IN A HORIZONTAL DIRECTION

摘要

The present invention relates to a battery cell. An electrode assembly which includes an anode, a cathode, and a separator interposed between the anode and the cathode, is installed in the receiving part of a battery case. A sealing part is formed on the outer surface of the receiving part by a thermal melting process. At least one of the sealing parts has an end which is bent to face the receiving part of the battery case. An electric insulating material is coated on the end of the sealing part bent.
