Electro Energy, Inc., is developing a unique bipolar Nickel-Metal Hydride (Ni-MH) rechargeable battery for a wide spectrum of applications, including the global EV battery marketplace. As a battery system, Ni-MH is receiving growing attention based on its coveted mix of excellent performance characteristics (energy density, cycle life, low temperature performance, and abuse tolerance), use of abundant materials, and its benign environmental nature (safe, nontoxic, recyclable). EEI's bipolar construction provides added energy density and rate capabilities in comparison to conventional Ni-MH batteries and enables significant cost savings, both through the simplicity of the wafer design as well as the synergistic use of low-cost plastic-bonded electrode technology. EEI's bipolar wafer cell construction is based on a sealable bipolar conductive plate which serves as both partition and series connection. This critical component has been found to be stable in a caustic environment. Cycle lives of over 2000 cycles in vented cells have been achieved with both foam nickel and plastic bonded-type nickel electrodes. Sealed cells have attained 2000+ cycles using a low-hydrogen overpressure metal hydride alloy. Results from multicell stacks are presented as well as preliminary results from EV-size cells. Simulated driving cycles have been used to evaluate cells through EV Dynamic Stress Tests. Extrapolating results of cell tests indicates that E.D.s of 80 W.h/kg and 225 W.h/l for full batteries are feasible.
