Abstract: front page image
(EN)The present invention relates to a pouch-type secondary battery, capable of increasing energy density, and a production method therefor. The secondary battery according to the present invention comprises: an electrode assembly which has a positive electrode plate, a negative electrode plate, and a separator formed in a wound manner, comprises a depressed part, depressed inwards from at least one side thereof, and comprises a pair of lead tabs drawn from the positive electrode plate and negative electrode plate; and a pouch comprising terrace parts formed by sealing the electrode assembly, wherein the pouch may be formed with the terrace parts folded in areas, other than the area in which the lead tabs are drawn.
(FR)La présente invention concerne une batterie rechargeable de type poche, permettant d’augmenter la densité d’énergie, et son procédé de production. La batterie rechargeable selon la présente invention comprend : un ensemble d’électrodes qui comporte une plaque d’électrode positive, une plaque d’électrode négative, et un séparateur formé d’une manière enroulée, comprenant une partie évidée, évidée vers l’intérieur depuis au moins un côté de celui-ci, et comprend une paire de pattes de connexion étendues depuis la plaque d’électrode positive et la plaque d’électrode négative ; et une poche comprenant des parties de gradin formées par scellement de l’ensemble d’électrodes, la poche pouvant être formée avec les parties de gradin pliées dans des zones autres que la zone dans laquelle les pattes de connexion sont étendues.
