摘要： A bipolar secondary battery comprises laminated bodies. The laminated body comprises bipolar electrodes laminated via an electrolyte layer. The bipolar electrode comprises a positive electrode active material layer and a negative electrode active material layer formed on surfaces of a current collector. A positive electrode is formed on one end of the laminated bodies and a negative electrode is formed on another end. A temperature sensitive resistor having a smaller area than an electrical reaction area of the positive electrode active material layer and the negative electrode active material layer is arranged between the positive electrode and the negative electrode of a pair of adjacent laminated bodies, thereby suppressing a temperature increase caused by a high current by increasing the resistance in response to the flow of the high current into the bipolar secondary battery such as when an external circuit is shorted.

摘要： A conductive film includes a layer 1 formed by a conductive material 1 that includes a polymer material 1 containing any of (1) an amine and an epoxy resin (where the epoxy resin and the amine are mixed in a ratio of 1.0 or more in terms of the ratio of the number of active hydrogen atoms in the amine with respect to the number of functional groups in the epoxy resin), (2) a phenoxy resin and an epoxy resin, (3) a saturated hydrocarbon polymer having a hydroxyl group, and (4) a curable resin and an elastomer and conductive particles 1. The conductive film has excellent stability in an equilibrium potential environment in a negative electrode and low electric resistance per unit area in the thickness direction. A multilayer conductive film including the conductive film achieves excellent interlayer adhesion, and using them as a current collector enables the production of a battery satisfying both weight reduction and durability.
