ABSTRACT:
A cylindrical lithium secondary battery includes an electrode assembly formed by stacking a first electrode plate having a first electrode tap, a second electrode plate having a second electrode tap, and a separator interposed between the first and second electrode plates. The first electrode plate, the second electrode plate and the separator are wound to form the electrode assembly. The secondary battery also includes a case for storing the electrode assembly and a cap assembly combined with an upper portion of the case to sealing the case. The radius of curvature of the second electrode tap is greater than the radius of curvature of the first electrode tap.
