Electro Energy Inc. (Nasdaq: EEEI), a leading provider of advanced battery technologies and associated systems, and In-Q-Tel, a private, not-for-profit venture group funded by the Central Intelligence Agency, today announced a new technology development agreement for advanced rechargeable bipolar lithium ion (BPLI) batteries. The resulting BPLI battery is intended to exhibit both high-specific energy and high-specific power, due to the efficiency of the EEEI bipolar cell and battery design. In previous work, EEEI has demonstrated BPLI cells with a specific energy greater than 200 Wh/kg and an energy density greater than 400 Wh/l. The development will be conducted at EEEI's battery manufacturing facility in Colorado Springs, Colorado.

Martin Klein, Chairman and CEO of EEEI, said, "We are extremely pleased with the capabilities of our prototype bipolar lithium ion technology. It has surpassed our expectations and will contribute importantly to military applications where high power, high energy density and low cost are critical advantages. In addition, we intend to bring this technology to the commercial sector for portable and mobile battery applications as soon as possible."

The EEEI bipolar lithium ion design- the result of an R&D program begun in March 2004- provides a very high surface area per unit of energy, which results in high power capability while minimizing wasted space and reducing weight and volume. When fully developed, the benefit potential over conventional batteries is lower cost, increased power density, longer life and improved reliability. In addition, the unique battery cell design will allow the battery to be configured in small areas and conform to other specialized design requirements.Simultaneously with the development agreement, EEEI is entering into an $800,000 stock purchase and warrant agreement with In-Q-Tel, announced earlier today. The purchase price for the stock and warrants is expected to be paid over the course of 14 months following the closing, conditioned upon EEEI achieving certain development milestones. No separate payments will be made or required under the development agreement.
