Innovation The firm has developed a lightweight high energy density battery

1. High Energy Density Silver-Zinc Cells Yardney, Pawcatuck, Connecticut • Innovation • The firm has developed a lightweight high energy density battery • optimized for the high cycle life and high energy density requirements. • Accomplishments • Energy Output: 40-90 watt-hours per pound and 2.5-8.0 watt-hours per cubic • inch, depending on cell type, model and conditions of use; as much as 120 • watt-hours per pound and 11.0 watt-hours per cubic inch for certain special • models and applications. • Power Output: From 50-150 watts per pound and 4-10 watts per cubic inch • (continuously) for "LR" Type Cells, to 150-500 watts per pound and 10-35 • watts per cubic inch (continuously) for "PM" Type Cells. On an intermittent • basis, values two times the indicated power output are possible (i.e., 1000 • watts per pound and 70 watts per cubic inch). • Open-Circuit Cell Voltage:1.82-1.86 volts when fully charged, 1.61-1.63 • volts when partially charged. • Nominal Voltage Under Load: m 1.5 volts. • Plateau Voltage Regulation: ± 2% at a fixed load and temperature limits • within ± 10°F Yardney Battery Products • Government/Science Applications • The firm has been extremely successful in capturing recent • contract opportunities such as supplying cells/batteries for • the MK-30 Navy target and the Swimmer Delivery • Vehicles for the Navy Seals. • The company has provided notable technological advances • for many different electro chemistries and is an • acknowledged leader in designing, developing and • fabricating high reliability cells, batteries and battery • systems for the following types of applications.Torpedo Applications Torpedo Target Applications Other Undersea Vehicular Applications Space Applications • Missile/Launch Vehicle Applications Satellite Applications Electronic Newsgathering (ENG) Application Oil Exploration Applications Portable Communications Equipment Applications Other Specialized Applications • Commercialization • The company has been very successful over the last few years in capturing market share and it’s revenue over the last year has increased by 80%. This growth is due to the the combination of capturing silver zinc battery production and the wide acceptance of Lithion`s rechargeable lithium ion technology. • Lithion Inc. and our customers will also benefit from a $13.7M contract sponsored by the US Air Force, the National Aeronautics and Space Administration and other US Federal Government Agencies, to develop cells and batteries of 7 to 200 Ah.
