Patent number: 8703331Abstract: A secondary battery including an intermediate layer having a pattern formed by carbon and a binder between a substrate and an active material layer and reinforcing adhesion between the substrate and the active material layer. In the intermediate layer, the carbon and the binder in the intermediate layer are adjacent to each other. Therefore, the active material is prevented from being detached from the substrate, thereby improving performance of the secondary battery. A small amount of the binder having strong adhesion is used in the active material slurry, thereby ensuring safety of the battery.Type: GrantFiled: April 18, 2012Date of Patent: April 22, 2014Assignee: Samsung SDI Co., Ltd.Inventor: Yong-Kyun Park
