Battery Modulation for Communications Equipment

The proposed Phase I work is to develop soft pack lithium polymer batteries with high energy density (>175 Wh/kg) and superior temperature performance. Ultralife has been engaged in lithium polymer battery research, development and manufacturing since1996. Ultralife has achieved several milestones in improving lithium polymer battery performance over the past year. The current Ultralife 34106102 polymer battery has an energy density of 160 Wh/kg with excellent cycling performance and high temperaturestorage performance (see the attached graphs). The Phase I project will incorporate high capacity cathode/anode active materials and non-flammable electrolytes to reach the capacity and performance requirements. The improved lithium polymer battery couldbe used in the hybrid portable power system for military and commercial applications. Ultralife will provide 20 cells for SOCOM qualification at the end of the Phase I project.
