Abstract
A secondary battery has a positive electrode plate and a negative electrode plate enclosed within an internal space of a housing. Positive and negative electrode terminals are plate-shaped, are respectively connected to the positive and negative electrode plates and extend externally from the housing at two different portions of the outer edge thereof. The positive electrode terminal has a first part fixedly adjoined to a second part formed of conductive material(s) having a higher tensile strength than those of the first part. The second part is located outside of the internal space, and a first end of the first part extends into the internal space while its second end is fixedly adjoined to the second part. The secondary battery disclosed herein may possess improved longevity and resistance to electrode terminal vibration.
