Abstract
A secondary battery includes first and second collecting plates branching out from an electrode terminal, and first and second electrode assemblies rolled up in a jelly-roll type unit, the first electrode assembly having a first non-coating portion adhered to the first collecting plate, the second electrode assembly having a second non-coating portion adhered to the second collecting plate, and the first and second collecting plates being on facing surfaces of respective first and second non-coating portions. The first non-coating portion is spaced apart from a roll center of the first electrode assembly by a first predetermined distance along a direction directed away from the second non-coating portion, and the second non-coating portion is spaced apart from a roll center of the second electrode assembly by a second predetermined distance along a direction directed away from the first non-coating portion.
