An electrode assembly of a lithium secondary battery is specially designed such that the positive and negative layers are formed at a side thereof with a large uncoated negative lead area and a large uncoated positive lead area. In addition, the collecting area is located correspondingly to the negative lead area or the positive lead area. And then the clasping assemblies are fixed outside the positive lead area or the negative lead area. In this way, the two pressing pieces are firmly pressed against the positive lead area or the negative lead area. On the one hand, the respective layers of the positive lead area or the negative lead area are pressed closely against one another, and on the other hand, the innermost layer of the positive lead area or the negative lead area is allowed to be maintained in a tight electrical contact with the collecting area. |
