Abstract
A rechargeable battery includes an electrode assembly comprising a positive electrode that has an uncoated region that is not coated with an active material along an edge, a negative electrode that has an uncoated region that is not coated with an active material along an edge, and a separator that is placed between the positive electrode and the negative electrode. The battery further comprises current collecting plates that are joined with the uncoated regions of the positive electrode and negative electrode while covering the uncoated regions, a case for housing the electrode assembly and the current collecting plates, and a cap assembly that is coupled with the case to seal it and includes terminals that are coupled with the current collecting plates.
