The Nickel Metal Hydride battery system has demonstrated its desirable power density, energy density, and life capabilities as an advanced battery for bikes, scooters, hybrid and all electric vehicles. However, battery cost is higher than desired thus limiting the full potential of this battery's use in the transportation sector. Electro Energy, Inc. (EEI) is engaged in the development of a bipolar design for the nickel metal hydride battery system that offers performance advantages and cost reductions when compared to conventional cylindrical and prismatic designs. The EEI design is based on the use of individual sealed flat rectangular wafer cells that are stacked on top of each other to make a series connected battery. Each wafer cell contains one positive electrode, a separator material, one negative electrode, and outer faces that serve as positive and negative contacts of the cell and contain the cell's electrolyte. To construct a multi-cell battery identical cells are stacked with end contacts and end plates to fabricate a complete assembly. For electric scooters and electric vehicles applications 500 Wh to 2 kWh modules are under development. Cost analysis of these modules in high-volume production show cost of materials of less than 200 Dollars/kWh and a predicted selling price of approximately 300 Dollars/kWh. Cells designed for hybrid electric vehicle applications contain 6 Ah capacity and have demonstrated over a thousand Watts/kg and up to 300,000 pulse cycles.
