摘要:
A surface treated electrode applicable to an electrode of a zinc-halogen secondary battery, etc. The surface plastic electrode includes (a) an electrically conductive electrode substrate material; and (b) a surface treatment material on the electrode substrate material, the surface treatment material being made of a phenol resin series activated charcoal fiber satisfying predetermined characteristic such that a weight per unit area substantially equal to 100 g/m.sup.2 or more, pore diameter having a distribution peak in a range from 1.5 nm to 3.5 nm, a surface area of a part substantially equal to or more than 30 m.sup.2 /g occupied by pores whose diameters range from 1 nm to 11 nm, a whole relative surface area of the entire pore diameter ranging substantially equal to or more than 1500 m.sup.2 /g, a tensile strength substantially equal to or more than 294 MPa (30 kg/mm.sup.2) and a tensile modulus substantially equal to or less than 14710.5 MPa (1500 kg/mm.sup.2). The conductive electrode substrate material is, for example, carbon plastic, glassy carbon, or Carbon-Carbon (C/C) composite. In the case of the C/C composite electrode substrate material, an ion exchange fiber is adhered onto one surface of the C/C composite electrode substrate material to form a three-layer type electrode.
摘要:
A process is provided for making a fluoroplastic molded-in insert without any supplementary production steps. A predetermined number of polytetrafluoroethylene bearers support a core material apart from the surface of a mold by a space equal to the desired thickness of a surfacing material to be formed on the surface of the core material. After disposing the bearers between a mold surface and the core material, hot-melt fluoroplastics are molded so as to combine the core material, the bearers and the hot-melt fluoroplastics into one unit. As a result, the core material is completely and simultaneously embedded when hot-melt fluoroplastics are molded.
