Abstract
An electrically conductive material containing no substantial amount of water and prepared by polymerizing, in the presence of an oxidizing agent, a compound having conjugated double bonds on a base material in a gas phase. The base material has spaces capable of retaining the oxidizing agent. The electrically conductive material is used for at least one electrode of a secondary battery.
Claims17
An electrically conductive material containing no substantial amount of water and oxidizing agent and prepared by polymerizing, in the presence of an oxidizing agent, a pyrrole or thiophene compound on a base material in a gas phase and then washing the resultant product with an organic solvent, wherein said base material has spaces capable of retaining said oxidizing agent and said electrically conductive material contains no substantial amount of said compound.
A secondary battery produced by using as at least one electrode of the anode and the cathode thereof, a film of an electrically conductive material containing no substantial amount of water and oxidizing agent and prepared by polymerizing, in the presence of an oxidizing agent, a pyrrole or thiophene compound on a base material having spaces capable of retaining said oxidizing agent in a gas phase, and then washing the resultant product with an organic solvent, wherein said film contains no substantial amount of said compound.
A secondary battery produced by using as at least one electrode of the anode and the cathode thereof, a film of an electrically conductive material prepared by treating with an oxidizing agent, a sheet of a base material having spaces capable of retaining said oxidizing agent, to retain said oxidizing agent only on one surface of said sheet, polymerizing a pyrrole or thiophene compound on said base material in a gas phase and then washing the resultant product with an organic solvent to thereby form a polymer of said compound on said one surface, wherein said film contains no substantial amount of water, said compound and said oxidizing agent.
A secondary battery produced by using as at least one electrode of the anode and the cathode thereof, a film of an electrically conductive material prepared by polymerizing, in the presence of an oxidizing agent, a pyrrole or thiophene compound on a metallic foam having porosity of 70 to 98% and having spaces capable of retaining said oxidizing agent in a gas phase, and then washing the resultant product with an organic solvent to thereby form a polymer of said compound in said spaces of said metallic foam.
A secondary battery produced by using, as at least one electrode of the anode and the cathode thereof, a film of an electrically conductive material prepared by treating with a solution of oxidizing agent in water, methanol or ethanol, a sheet of a base material having spaces capable of retaining said oxidizing agent to retain the oxidizing agentof said solution only on one surface of said sheet, polymerizing a pyrrole or thiophene compound on said base material in a gas phase and then washing the resultant product with an organic solvent to thereby form a polymer of said compound on said one surface, wherein said film contains no substantial amount of water, said compound and said oxidizing agent.
