Abstract
A secondary battery includes an electrode assembly including a first electrode plate, a second electrode plate, and a separator between the first electrode plate and the second electrode plate, a case in which the electrode assembly and an electrolyte are received, and a finishing member attached to an outer surface of the electrode assembly. The finishing member includes a first layer, a second layer, and a third layer. The first layer has one surface attached to the electrode assembly. The second layer and the third layer are different from each other and are sequentially provided on another surface of the first layer. The second layer and the third layer react to the electrolyte.
