Abstract: A secondary battery includes an electrode assembly having a positive electrode, a negative electrode and a separator interposed between those two electrodes. The secondary battery also includes a container for receiving the electrode assembly inside thereof; a cap assembly electrically connected to the electrode assembly and fixed to the container to seal the container; collector plates electrically connected to the positive electrode and the negative electrodes, and an auxiliary collector plate disposed between at least either the positive or negative electrode and the collector plate corresponding to that electrode.

Abstract: A secondary battery includes an electrode group with both positive and negative electrodes and a separator interposed therebetween and a case wherein the electrode group is located. A cap assembly is combined with the case, seals it, and is electrically connected to the electrode group. Collecting plates are electrically connected to the uncoated region of the positive and negative electrodes. The respective collecting plates have a plurality of holes thereon, and may be located at both the top and the bottom of the case so that electrolyte infusion can be rapidly and easily performed.

Abstract: The present invention provides a secondary battery including an electrode assembly comprising positive and negative electrodes with a separator interposed therebetween and wound together, a case, a cap assembly, and a negative current collecting plate. The negative current collecting plate includes a partially surface-treated region for fixing the negative current collecting plate to the negative electrode. The partially surface-treated region comprises a metal other than the metal of the negative current collecting plate. The use of a metal other than the metal of the negative current collecting plate provides an improved weld between the negative current collecting plate and the negative electrode which in turn provides improved battery performance, especially for high-load batteries.

Abstract: A secondary battery includes: an electrode assembly including positive and negative electrodes; a container adapted to receive the electrode assembly; a cap assembly having at least two terminals exposed outside the container, the cap assembly being adapted to be fixed to the container to seal the container; and lead elements adapted to electrically connect the terminals and the electrode assembly. A center of the terminals are aligned with a center of the electrode assembly, and the lead elements are spaced apart from the center of their respective terminals and adapted to be connected to their respective terminals and the electrode assembly.

Abstract: A rechargeable battery comprises an electrode assembly including a positive electrode, a negative electrode, and a separator interposed therebetween. The battery further comprises a case for housing the electrode assembly, a cap assembly coupled with the case, and a collecting plate having a first fixing portion coupled with the positive electrode or the negative electrode and a second fixing portion coupled with the case. A buffer portion is provided between the first fixing portion and the second fixing portion to alleviate forces exerted on the collecting plate.
