Abstract
To provide a secondary battery that can be prevented from exploding or catching fire due to the occurrence of a short circuit. The secondary battery (10) of the present invention includes an electric cell assembly that is, at least, partially enclosed by an extensible sheet (11) having a surface resistivity of 10−2 Ω/sq to 1010 Ω/sq, and is housed together with an electrolyte in a container (5), and in which positive electrodes (1) and negative electrodes (2) are stacked on each other or wound with a separator (3) interposed therebetween.
