PROBLEM TO BE SOLVED: To suppress generation of a large current, a spark and an intense heat caused by internal short-circuiting in a lithium secondary battery, even when a lithium dendrite is generated while using the battery. SOLUTION: In a lithium secondary battery composed of a positive electrode 2, a negative electrode 4 to occlude a lithium ion or deposit it as a lithium metal and electrolyte 1, a porous molding body 3 comprising a conductive macromolecular capable of N type doping, which is connected electrically to the positive electrode 2 by way of a connecting strip placed outside the electrolyte without touching the negative electrode between the positive electrode 2 and the negative electrode 4, is arranged. |
