Abstract:
(EN) An electrode assembly according to an embodiment of the present invention has a first electrode including a first electrode activation part and a first uncoated electrode part, a separator, and a second electrode including a second electrode activation part and a second uncoated electrode part being stacked and wound around a winding axis, wherein the first electrode activation part comprises a first small electrode part including a first substrate and first active material layers respectively formed on both surfaces of the first substrate, and a second small electrode part including an exposed surface of the first substrate, wherein the first active material layer is formed on the other surface of the first substrate, and wherein the second small electrode part is located in a first curved surface part that is created by first rotation of the electrode assembly.
(FR) Un ensemble d'électrodes selon un mode de réalisation de la présente invention comprend une première électrode comprenant une première partie d'activation d'électrode et une première partie d'électrode non revêtue, un séparateur, et une seconde électrode comprenant une seconde partie d'activation d'électrode et une seconde partie d'électrode non revêtue empilées et enroulées autour d'un axe d'enroulement, la première partie d'activation d'électrode comprenant une première petite partie d'électrode comprenant un premier substrat et des premières couches de matériau actif respectivement formées sur les deux surfaces du premier substrat, et une seconde petite partie d'électrode comprenant une surface exposée du premier substrat, la première couche de matériau actif étant formée sur l'autre surface du premier substrat, et la seconde petite partie d'électrode étant située dans une première partie de surface incurvée qui est créée par la première rotation de l'ensemble d'électrodes.
