The use of (CH)x films as electrode-active materials in three different types of rechargeable battery cells is described. The electrochemical characteristics of (CH /sup +/y)x electrode is specified. Oxidation, coloumbic efficiency, and energy efficiency are determined. Maximum power densities are obtained. Polarization studies investigating the constant current discharge density, and the degree of oxidation of the polyacetylene, and other parameters, were made. These studies indicate that cells involving neutral and/or partly reduced polyacetylene have excellent stability and exhibit interestingly large energy and power densities even at relatively small levels of reduction of the polyacetylene. The electrochemical characteristics of all the (CH) /SUB x/ cells are extremely sensitive to the method of cell construction, presence of impurities (especially oxygen), relative ratio of electrolyte to (CH) /SUB x/ , and method of charging.
