<P>PROBLEM TO BE SOLVED: To provide a laminated secondary battery in which heat shrinkage of openings of bag-shaped separators is suppressed under high temperature environment and short circuit between laminated electrodes is prevented. <P>SOLUTION: In the laminated secondary battery of this invention, positive electrodes 13 and negative electrodes, each of which has an extraction terminal 2, are alternately laminated via separators 15. At least one of the positive electrodes 13 and negative electrodes are housed in a bag-shaped separator bag 15, which is formed by bonding two sheet separators and has an opening 3. Further, the extraction terminal 2 of each electrode 13 housed in the separator bag 15 protrudes outside of the separator bag 15 through the opening 3, and an outer periphery of the opening 3 is covered by an electrical insulation layer 8. <P>COPYRIGHT: (C)2012,JPO&INPIT |
