Title:
MANUFACTURE OF POLARIZABLE ELECTRODE
Document Type and Number:
Japanese Patent JPH01298712
Kind Code:
A
Abstract:

PURPOSE: To improve adhesive properties of carbon fiber woven cloth and current collector by preheating the woven cloth, flame spraying conductive metal on the cloth to form the collector, and then smoothening the surface of the collector with a hot pressure roller.

CONSTITUTION: Carbon fiber woven cloth is fed out of a drum 8 in which the cloth is wound, and passed through a preheating furnace 8 to preheat the cloth. The thickness of the cloth is generally 0.3W1.0mm. Conductive metal is flame sprayed from a flame spraying gun 10 to one side surface of the preheated cloth to form a current collector. As the metal, Al, Ni, Cu, Ti, etc., which are electrochemically stable for electrolyte are employed. The thickness of the sprayed film, i.e., the collector is preferably 100W300μm. A laminate 1 of the cloth and the collector is hot pressed by a hot pressure roller 11 to smoothen the surface of the collector. Thus, the sprayed metal is impregnated into the cloth, and an electrode having high adhesive properties of the cloth and the collector is obtained.
