Electrode substrate and manufacture thereof
专利汇可以提供Electrode substrate and manufacture thereof专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain an electrode substrate having thick size, good conductivity, and large compression repulsion by stacking fabrics or knits made of fire resistant fibers and a nonwoven fabric, punching to entangle the fibers, and carbonizing. CONSTITUTION:Fire resistant fibers which are a precursor of carbon fiber such as polyacrylonitrile fiber are heated at 150-400 deg.C, and fabrics or knits made of these fibers and nonwoven fabrics are alternately stacked to obtain specified thickness. The stack obtained is punched with a needle punch to entangle fibers, then heated in a nitrogen atmosphere, for example, at 1300-3000 deg.C to obtain carbon fibers. By this process, an electrode substrate having a specified thickness, low electric resistance in the thickness direction, and large compression repulsion is obtained. This substrate is effective as the electrode substrate of a redox-flow cell or a sodium-sulfur battery.，下面是Electrode substrate and manufacture thereof专利的具体信息内容。
