PROBLEM TO BE SOLVED: To secure the adhesion between positive/negative electrodes and a separator and thin the battery by providing the separator which is arranged between the positive electrode and the negative electrode and formed by retaining electrolyte including polymer retaining nonaqueous electrolytic solution and electrolytic solution in a porous insulating sheet. SOLUTION: Polymer lithium secondary battery is provided with a power generating element mainly composed of a material formed by integrally forming a positive electrode 1, a negative electrode 2, and a separator 3 arranged between the positive electrode 1 and the negative electrode 2 with one another. The separator 3 is formed by retaining electrolyte including polymer retaining nonaqueous electrolytic solution and electrolytic solution in a porous insulating sheet. A positive electrode lead 12 composed of a belt aluminum plate is connected to a positive electrode terminal 10 and a negative electrode lead composed of a belt copper plate is connected to a negative electrode terminal 11. The power generating element of this constitution is sealed in an external material 14 having a barrier function relative to the moisture with the positive electrode lead 12 and the negative electrode lead extended from the external material 14. |
