NOVELTY - Bipolar electrode battery comprises a collector (10) containing a high-polymer material, a cathode (20) electrically connected to a first side of the collector, an anode (40) electrically connected to a second side of the collector, and electrolyte layer(s) (30) overlying the cathode and anode.    USE - As a bipolar electrode battery and useful for fabricating a battery module useful in a vehicle (claimed).    ADVANTAGE - In the collector of the bipolar electrode battery, the electrode charge generated in negative electrode is directly supplied to positive electrode. Therefore, the electric current flows in the direction of the laminated layer that is structural element of the bipolar electrode battery and does not have to flow in the horizontal direction. As a result, to decrease the electric resistance in the horizontal direction, the metal foil used in conventional battery is not necessary. Since the electric resistance in the horizontal direction can be high, the thickness can be thin. By making collector from high-polymer material, it is possible to trim the weight of the collector and improve the energy density of the battery without reducing battery performance. The electric current flows in the vertical direction through the collector from the one electrode to the other electrode, and the conductivity in the vertical direction is provided by conductive particles or conductive high polymer film. As a result, it is possible to decrease the mass of the collector. Since the collector uses the conductive particles and high-polymer material, the contact of the collector with the conductive additive inside the electrodes improves. It is possible to provide electric vehicle and hybrid vehicle with good mileage and excellent driving performance.    DETAILED DESCRIPTION - The collector further comprises several electrically conductive particles that have a high binding property to the high-polymer material. The electrically conductive particles are metal particles or carbon particles. The high-polymer material can be an electrically conductive polymer. The battery further comprises an electrode extracting plate (11) electrically connected a side of the collector. The high-polymer exhibits a weight average molecular weight of 50000 - 1000000 Daltons. An INDEPENDENT CLAIM is included for manufacturing the bipolar electrode battery/assembly.
