POLYACETYLENE COMPOSITE, PROCESS FOR PRODUCTION THEREOF, AND METHOD FOR USE THEREOF |
摘要 |
<p>Polyacetylene composite comprising a polyacetylene polymer being coated with at least one of the ionic organic compounds 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 a quite high stability to the n-doped polyacetylene and therefore the secondary battery using it as a negative electrode active substance amazingly excells in terms of protracted charge-discharge cycle property, self-discharge property, and voltage-maintaining property.</p> |
