Clyde Space has been awarded an Innovation Triangle Initiative (ITI) contract from the European Space Agency (ESA) to perform characterization and qualification testing on a Lithium Polymer Cell battery to demonstrate its suitability for use on Small Satellites. The key advantages of a lithium polymer cell is its lightweight, high energy density and slim, volume efficient geometry. The cell uses a polymer electrolyte and is packaged in a foil bag, which provides both mass and magnetic signature advantages. This ESA contract follows on from an ESA Study in 2005, which evaluated the use of lithium polymer technology in space; the study produced some encouraging results; in particular, a cell that performed well in reduced pressure environments and over a wide temperature range.
