There are provided method and apparatus for manufacturing a polarizable electrode for electric double layer capacitor is provided which is capable of preventing porosities, cracks, or breakage of a sheet as much as possible when molding materials are formed into a sheet form and improving the yield of the molding materials. The manufacturing apparatus is used before granulated molding materials that are finely divided and crushed are moved to a calendar molding machine. The apparatus includes a mixing machine, a vibrating sieve, and a vibrating feeder. In the mixing machine, when the granulated molding materials are mixed with IPA as a binding assistant in a hermetically sealed mixing container, they are agitated by agitating blades. With this, even when during the mixing, the granulated molding materials adhere with each other to form lumps, the lumps are crushed by the agitation of the agitating bladesso that the molding materials are disintegrated into smaller particles. The molding materials mixed with IPA are sieved by the vibrating sieveand conveyed to the calendar molding machinealong a conveyance pathof the vibrating feeder, whereby the molding materials are formed into a sheet form.

A high temperature sliding alloy has a matrixof a Ni-base alloy or a heat resistant Fe-base alloy, and contains, by mass, 1 to 35% hard particles consisting of a Co-base intermetallic compound dispersed therein, wherein 0.1 to 10% Ag is dispersed in the matrix. Ag is a soft metal, forms an ultrathin film on a sliding surface caused by sliding with a mating member, and presents a lubricating effect. When Ag forms the ultrafine film and spreads on the sliding surface, it works little as a frictional force against the mating member due to its low shear resistance, and accordingly can achieve a low coefficient of friction.

A method of making a polarizable electrode for an electric double layer capacitor, includes adding a binder assistant to a binder so that the binder is swollen and mixing a carbonaceous powder, a conductive assistant and thereafter the swollen binder, thereby obtaining a material mixture, kneading the material mixture into a primary forming material, forming the primary forming material into a secondary forming material, and rolling the secondary forming material into a sheet shape.

Method of making polarizable electrode for electric double layer capacitor

A sheet electrode with a predetermined thickness for an electric double layer capacitor is made by carrying out a roller rolling step in which a long sheet intermediate is made from a material containing a carbonaceous powder, a conductive assistant and a binder and thereafter. The sheet intermediate is passed between a pair of rolling rollers to be wound up by a winding section while being drawn out of a drawing section. The roller rolling step includes drawing the sheet intermediate out of the drawing section under a predetermined tension applied to the sheet intermediate, and controlling a widthwise position of the sheet intermediate immediately before the rolling rollers by an edge position controller, and winding the sheet intermediate rolled by the rollers onto a winding section while the winding section is applying a predetermined pressure to a rolling side drive roller located adjacent to the winding section and rotated at a predetermined speed.
