PROBLEM TO BE SOLVED: To avoid generation of a short circuit between electrode terminals, even when external force is applied at the falling or the like. SOLUTION: An expression (A-a)+(B-b)<L (where A>=a and B>=b) is satisfied, where A represents the length of pisitive electrode terminal 2, (a) represents its width, B is the length of a negative electrode terminal 3, (b) is the width thereof, and L represents the space between the positive electrode 2 and the negative electrode 3, in a polymer lithium secondary battery having such structure that it has positive electrodes 6a, 6b storing/releasing a lithium ion, lithium ion-conductive polymer electrolytes 5a, 5b, and a negative electrode 4 storing/releasing the lithium ion, and that the positive and negative electrodes 2, 3 are led out in the same side. |
