LAMINATED-TYPE BATTERY AND METHOD OF MANUFACTURING SAME
Document Type and Number:
Japanese Patent JP2010232145
Kind Code:
A
Abstract:

To provide a laminated-type battery capable of fixing a laminated electrode body firmly without shifts, while suppressing reduction in the battery capacity.

In a laminated electrode body 10 of a laminated-type battery, in a low activity region N1 that deviates from an active region H1 that is apt to be utilized in an electrode reaction substantially, through-parts 31, 32 for preventing the shift in a lamination, penetrating through a positive electrode plate 1 and a negative electrode plate 2 in the direction of lamination are provided, and the laminated electrode body 10 is fixed by the through-parts 31, 32, and thereby, the low active region N1 that is not utilized sufficiently in an electrode reaction is made to be utilized effectively.
