Abstract
A reinforced acetylene high polymer shaped article is provided, which is comprised of an acetylene high polymer and 10 to 500 wt. parts, per 100 wt. parts of the acetylene high polymer, of a sheet-form product of a fibrous material. The reinforced acetylene high polymer shaped article is prepared by polymerizing acetylene in the presence of the sheet-form product coated or impregnated with a catalyst solution, or by superposing the acetylene high polymer upon the sheet-form product and then pressing or calendering the superposed assembly. The reinforced acetylene high polymer shaped article is useful particularly as an electrode of a battery.
Claims57
A battery comprising a positive electrode, a negative electrode and an electrolyte, wherein at least one of said positive electrode and said negative electrode is comprised of a reinforced acetylene high polymer shaped article, which comprises (1) an acetylene high polymer or an electroconductive acetylene high polymer doped with a dopant, and (2) 10 to 500 parts by weight, per 100 parts by weight of the acetylene high polymer, of the sheet-form product of a fibrous material, and which is prepared by shaping under pressure a swollen or gel-like acetylene high polymer containing an organic solvent, together with said sheet-form product;
- said sheet-form product being a woven or knitted fabric, a non-woven fabric or a net or screen, which is composed of an organic high polymer fiber or an inorganic fiber, and said acetylene high polymer being prepared by polymerizing acetylene using a catalyst system comprised of a transitional metal compound and an organic metal compound, said transitional metal compound being used in an amount of 0.0001 to 0.1 mole per liter of a polymerization solvent.
