Original Abstract Submitted
A secondary battery includes an electrode assembly including a positive electrode plate having a positive electrode non-coating portion, a negative electrode plate having a negative electrode non-coating portion, and a separator between the positive and negative electrode plates. The positive and negative electrode non-coating portions are exposed at opposite sides of the electrode assembly. The secondary battery also includes a case having a top opening and an internal space accommodating the electrode assembly, a cap plate sealing the top opening of the case, a positive electrode current collector plate perpendicular and welded to the positive electrode non-coating portion, a negative electrode current collector plate perpendicular and welded to the negative electrode non-coating portion; a positive electrode terminal on the cap plate and electrically connected to the positive electrode current collector plate, and a negative electrode terminal on the cap plate and electrically connected to the negative electrode current collector plate.
