摘要： A battery includes an electrode assembly fabricated with a positive electrode, a separator, and a negative electrode, each perforated by corresponding through voids along both of their respective opposite edge margins, stacked one upon another with the corresponding holes aligned. An arrangement of guide portions integrally formed simultaneously together with a surrounding case, accommodates stacking of the electrode assembly during fabrication of the battery. Aspects of the guide portions extend along a direction of stacking of the positive electrodes, negative electrodes and separators. The case and the arrangement of guide portions improve the internal alignment and facilitates the stack ability of electrode assemblies formed by the stacking of positive electrodes, negative electrodes and separators, and enhances the operational stability of the battery and the output performance of the battery, without detracting from the overall compactness of the battery.
