Beschreibung
Zusammenfassung:	The present invention relates to a pouch-type lithium secondary battery comprising: an electrode assembly which includes an anode, a separator, and a cathode; and a pouch which has a groove for accommodating the electrode assembly and an edge of which the upper and lower parts are formed in a flange type by being bonded around the groove, wherein in at least a part of the edge that is formed in the flange type, an end of the edge is covered by a flame retardant and heat resistant resin composition wherein a flame retardant material and a heat resistant material are mixed to a thermoplastic resin or a thermosetting resin, thereby improving safety.
