The charge-discharge characteristics of the anion-doped lithium-polyacetylene left bracket (CH)//x right bracket battery was investigated by means of the FFT impedance method, by which the impedance-frequency dispersion could be measured by very high speed. The charging and self-discharging of the Li-(CH)//x battery were represented by the Randles-type equivalent circuit, added with the corrective term concerned with surface roughness. These processes and their doping states of the (CH)//x film were readily detected by the variation in the resistive component, Rr, in the equivalent circuit.
