The core structure has an electrode assembly (40) with a positive layer (41), separating layer (42) and negative layer (43) that is wound around a core (30). Two conductive fixing assemblies (50) has conductive pressing elements (52) that are positioned outside the positive lead region (411) and negative lead region (431) and are fixed to core by inserting fasteners (51) through the holes (521) of the pressing elements such that positive and negative lead regions are maintained at close electrical contact with pressing elements. |
