摘要： A secondary battery includes a first electrode plate, a second electrode plate, a separator interposed therebetween, and at least one insulation member. The first electrode plate has a first electrode collector having at least one surface on which a first electrode active material is coated to form a coating portion, a first electrode uncoated portion formed on at least one end of the first electrode collector, and a first protrusion formed on at least one end of the electrode coating portion. The second electrode plate includes a similar second electrode collector, a second electrode coating portion, a second electrode uncoated portion, and a second protrusion. The separator insulates the first electrode plate from the second electrode plate. The at least one insulation member is formed on and covers the first protrusion, the second protrusion, or both such that an electrolyte is flowable through the at least one insulation member.
