  • Patent number: 9450266
    Abstract: A battery main body housed in a case comprises one laminated body composed of a plurality of bipolar electrodes laminated with an electrolyte layer therebetween or comprises a plurality of laminated bodies connected in series. A positive electrode current collecting plate and a negative electrode current collecting plate each having one surface joined to the inner peripheral surface of the case and the other surface joined to one end of the battery main body respectively extend to the outside of the case. By providing a cutoff mechanism for cutting off an electrical connection between the positive electrode current collecting plate and the negative electrode current collecting plate via the battery main body according to an expansion deformation of the case, a current path in a bipolar secondary battery is interrupted when the short-circuit current occurs, thereby protecting the bipolar secondary battery from a short-circuit current.

  • Patent number: 8900734
    Abstract: 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.
