When oxidized in a nonaqueous cell containing in propylene carbonate, polyacetylene develops a voltage of 3.4–4.0V vs. . Oxidation levels at least as high as can be produced electrochemically and then reduced to the undoped state with nearly 100% coulombic efficiency. The electrochemical doping (oxidation) process is only efficient when carried out with a minimum of liquid electrolyte under ultraclean conditions. Similar results are observed with a electrolyte. Polyacetylene is an extraordinary material of great importance for electrochemistry. However, on the basis of this and other published research, it is not yet clear that it offers major advantages over current electrodes for high energy density nonaqueous batteries.
