A secondary battery includes at least one first electrode plate, at least one second electrode plate and separators. The first electrode plate has a first active material layer intermittently coated in the length direction thereof and a first non-coating portion on which the first active material layer is not coated. The first non-coating portion is folded. The second electrode plate is alternately positioned with the first electrode plate, and has a second active material layer intermittently coated in the length direction thereof and a second non-coating portion on which the second active material layer is not coated. The second non-coating portion is folded. The separators are positioned between the respective first and second electrode plates. The secondary battery further includes first and second electrode tabs that respectively clamp at least one of the first non-coating portions and at least one of the second non-coating portions.
