Title:
非水電解質二次電池
Document Type and Number:
Japanese Patent JP7108358
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery which is obtained by covering an electrode plate group with a laminate film and heat-sealing the covered electrode plate and is not affected by heat by heat sealing.SOLUTION: A nonaqueous electrolyte battery which is not affected by heat during heat sealing is obtained by setting the heat seal width of a portion for deriving a terminal of a laminate film that covers an electrode plate group formed by alternately laminating a positive electrode and a negative electrode via a separator to 5 mm or more, and setting a value of L1/L2 when the heat seal width is L1 and the length from a connection portion of the terminal connected to the positive electrode and the negative electrode to a heat seal portion is L2 to 1.0 or less.SELECTED DRAWING: Figure 1
