<P>PROBLEM TO BE SOLVED: To enhance the cycle characteristics by equalizing the battery reaction between the regions in the laminate electrode body of a nonaqueous electrolyte secondary battery in which the laminate electrode body, to which a tape is stuck to the laminate upper surface, the end face and the laminate lower surface, is housed in a housing. <P>SOLUTION: A laminate electrode body 10 is configured by laminating a plurality of positive electrode plates and negative electrode plates with a separator therebetween. On the outer periphery of the laminate electrode body 10, tapes 21-24 are stuck to the laminate upper surface 10a, the end face 10c, and the laminate lower surface 10b in the laminate electrode body 10 across the laminate electrode body 10 in the lamination direction. The base material of each tape 21-24 is formed of any one of styrene butadiene rubber, styrene rubber or butadiene rubber. <P>COPYRIGHT: (C)2013,JPO&INPIT |
