A core structure for a square lithium secondary battery comprises: a core, an electrode assembly, and two conductive fixing assemblies. The respective layers of the positive and negative lead areas are clamped together by the conductive pressing pieces, therefore, the structure of the present invention is simple. In addition, the respective layers of the positive and negative lead areas are pressed against and in electrical contact with one another directly. Therefore, the internal resistance of the present invention is relative low, and is suitable for use in the high capacity battery case. |
