Abstract
Polyacetylene composite comprising a polyacetylene polymer coated with at least one ionic organic compound such as alkali metal alkoxide type compounds of 1,2-diol, semicarbonic ester derivatives of 1,2-diol, and ortho-ester derivatives; a process for the production of the above composite characterized by applying a solution of the above ionic organic compounds to the polyacetylene polymer; a process for the production of the above composite characterized by placing the polyacetylene polymer as an electrode in an electrolyte containing a cyclic carbonic ester compound and an alkali metal ion and electrochemically reducing the cyclic carbonic ester compound; and a process of using an n-doped polyacetylene composite as a negative electrode active substance for a secondary battery. The ionic organic compound provides high stability to the n-doped polyacetylene and therefore the secondary battery using it as a negative electrode active substance has outstanding protracted charge-discharge cycle properties, self-discharge properties, and voltage-maintaining properties.
