Abstract:
A bipolar secondary battery includes a plurality of bipolar electrodes, each including a current collector that has a positive electrode layer on one surface thereof and a negative electrode layer on the opposite surface thereof. A separator is disposed between adjacent two bipolar electrodes such that the positive electrode layer of one bipolar electrode and the negative electrode layer of the adjacent bipolar electrode adjacent are opposed to each other along the length of the separator. The positive electrode layer and the negative electrode layer are formed with protrudent portions disposed at positions offset from each other along a length of the current collector.
