Title (EN) LITHIUM ION SECONDARY BATTERY
(FR) ACCUMULATEUR LITHIUM-ION
(KO) 리튬 이온 이차전지
Abstract:
(EN) A lithium ion secondary battery is disclosed. According to the present invention, a secondary battery capable of easily changing a capacity, a voltage, or the like according to user demand can be manufactured. To this end, the present invention comprises: first and second electrode laminates in which a cathode, a separator, and an anode, each including at least one line segment on the periphery thereof, are alternately laminated; and a cathode tab and an anode tab, each having a shape protruding from the line segments of the cathode and the anode, wherein the cathode, the separator, and the anode are laminated such that the segments thereof face each other, the cathode tabs are laminated such that the cathode tabs face each other, thereby forming a cathode tab bundle, the anode tabs are laminated such that the anode tabs face each other, thereby forming an anode tab bundle, the second electrode laminate is connected to a side of the first electrode laminate, and the cathode tab bundle and the anode tab bundle of the first electrode laminate are connected to the cathode tab bundle and the anode tab bundle of the second electrode laminate, the electrode tab bundles being the same as or different from each other.
(FR) L’invention concerne un accumulateur lithium-ion. Selon la présente invention, un accumulateur pouvant changer facilement une capacité, une tension, ou similaire selon la demande de l’utilisateur peut être fabriqué. À cette fin, la présente invention comprend : de premier et deuxième stratifiés d’électrodes dans lesquels une cathode, un séparateur, et une anode, incluant chacun au moins un segment de ligne sur leur périphérie, sont stratifiés alternativement ; et une languette de cathode et une languette d’anode, ayant chacune une forme en saillie depuis les segments de ligne de la cathode et de l’anode, la cathode, le séparateur, et l’anode étant stratifiés de sorte que leurs segments se font face, les languettes de cathode étant stratifiées de sorte que les languettes de cathode se font face, formant ainsi un faisceau de languettes de cathode, les languettes d’anode étant stratifiées de sorte que les languettes d’anode se font face, formant ainsi un faisceau de languettes d’anode, le deuxième stratifié d’électrodes étant connecté à un côté du premier stratifié d’électrodes, et le faisceau de languettes de cathode et le faisceau de languettes d’anode du premier stratifié d’électrodes étant connectés au faisceau de languettes de cathode et au faisceau de languettes d’anode du deuxième stratifié d’électrodes, les faisceaux de languettes d’électrodes étant identiques ou différents les uns des autres.
