Polyacetylene can be electrochemically reduced in tetrahydrofuran containing dissolved LiC1O/sub 4/ t form compositions of the type, (Li /SUB y/ CH) /SUB x/ . The reduction occurs with high coulombic efficiency for doping levels of y < 0.10. Reduced polyacetylene in this composition range appears to be quite stable in this particular electrolyte. The potential of (Li /SUB y/ CH) /SUB x/ is 0.5-1.5V positive of that of Li. Compared with Li as a nonaqueous battery negative electrode, (Li /SUB y/ CH) /SUB x/ has considerably lower gravimetric and volumetric energy densities and a higher electrochemical potential.
