Abstract : The object of the research conducted under this contract is to evaluate polyacetylene (CHx) as a replacement for carbon as the cathode material in primary lithium/thionyl chloride (Li/SOC12) and lithium/sulfur dioxide (Li/SO2) batteries. The choice of the Li/SOC12 inorganic electrolyte cell is based on the fact that it is the highest energy density system known to date. By itself, the favorable ratio of obtainable work to weight is not sufficient. For Navy applications, the rate at which the cell supplies energy - the power density - is very important. CHx is a lightweight material with extremely high effective surface area (60 m squared/g) and good electrical conductivity when doped, thus making it a good candidate for an electrode in a high power density cell.
