The new battery is intended to exhibit high-specific energy and high-specific power, due to the efficiency of the EEEI bipolar cell and battery design. In previous work, EEEI demonstrated BPLI cells with a specific energy greater than 200 WH/kg and an energy density greater than 400 WH/l. 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 benefits over conventional batteries will be lower cost, increased power density, longer life and improved reliability.
