Abstract
A secondary battery includes an electrode assembly, a case and a safety member. The electrode assembly has a first electrode plate, a second electrode plate and a separator interposed between the first and second electrode plates. The case accommodates the electrode assembly, and has an opened top. The safety member is inserted into an upper inside portion of the case, and seals the case. In the secondary battery, the safety member comprises an outer member contacting an inner surface of the case and having a center passing therethrough, an inner member spaced apart from the outer member at a predetermined interval and positioned at the center of the outer member, and a connection member connecting the outer and inner members. Accordingly, it is possible to increase the capacity of the battery.
