Abstract

A pouch type secondary battery, in which a bent state of a cathode tap and an anode tap is maintained by eliminating a restoration phenomenon caused by an elastic force of the insulating tape when the cathode tap and the anode tap are bent by forming bending grooves on cathode and anode insulating tapes, includes: an electrode assembly which includes a cathode electrode plate where a cathode tap is connected, a anode electrode plate where an anode tap is connected, and a separator interposed between the cathode electrode plate and the anode electrode plate; a pouch containing the electrode assembly therein such that the cathode tap and the anode tap are exposed to the outside; a cathode insulation tape forming a first bending groove on at least one side portion and wrapped around the cathode tap so as to insulate a region where the cathode tap is in contact with the pouch; and an anode insulation tape forming a second bending groove on at least one side portion and wrapped around the anode tap so as to insulate a region where the anode tap is in contact with the pouch.
