<P>PROBLEM TO BE SOLVED: To provide a laminate type secondary battery which makes a trouble due to an erratic electrode lamination less liable to occur. <P>SOLUTION: The laminate type secondary battery comprises: a plurality of first electrodes 2; a plurality of first current collection tabs 5a; a plurality of first separators 4a which is dividable into a first portion and a second portion by a central axis A; a plurality of second electrodes 3, one portion of which dividable into halves by central axis B opposes the first portion and the other portion of which opposes the second portion; and a plurality of second current collection tabs 5b. In the first portion of each of the first separators 4A is formed a first asymmetric portion 7 which is asymmetrical about the second portion and the central axis A; in one portion of each of the second electrodes 3 is formed a second asymmetric portion 8 which is asymmetrical about the other portion and the central axis B, where all of the first asymmetric portions 7 and all of the second asymmetric portions 8 match in the laminate direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
