<P>PROBLEM TO BE SOLVED: To provide a means capable of balancing high output density with high energy density in a secondary battery mounted on a vehicle or the like. <P>SOLUTION: This battery pack is so composed that a bipolar battery and a general battery group composed by serially connecting general batteries by the number of combination structures of the positive electrodes and the negative electrode of the bipolar battery are connected in parallel with other. The battery pack is characterized by that the battery capacity of the general battery group is larger than that of the bipolar battery. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
