Electro Energy is focused on three battery technologies: Bipolar Nickel Metal Hydride, Bipolar Lithium Ion and Super Ni-Cd Prismatic. Our unique technologies provide superior performance in energy capacity, size and weight vs competitors.

EEI's Bipolar Nickel Metal Hydride (BNMH) batteries use a unique and patented flat wafer cell design developed over the past 12 years. The cells can be made in any shape and are therefore applicable to a wide variety of military and commercial applications. Wafer cells are stacked one on top of another to create multi-cell batteries with the required energy capacity and voltage for a given application. EEI has supplied prototype BNMH batteries to various commercial and government customers.

Compared to the competitor's high power NiCad, EEI packages NMH at the same weight and volume to provide 40% more energy and 50% higher power, or EEI could provide up to 36Volts in the same package.

Applications that EEI is targeting with our Bipolar Nickel-Metal Hydride batteries include the automotive industry, where battery technology is needed to support the rapidly growing gasoline/electric hybrid market and manufacturers upgrading to more powerful 42 volt starting batteries from the 12 volt systems used today. The electric scooter/bicycle market is also large, particularly in Asia where governments are encouraging a switch to electric power to reduce pollution. EEI believes that high performance electric scooters have a market in the US also and is searching for a partner in this market. The cordless power tool market is rapidly growing and EEI batteries provide better energy capacity and a better environmental profile.
