ABSTRACT:
A composite electrode for a photo-rechargeable storage battery includes a filter paper of glass fiber as a base material; a polypyrrole film coated on a surface of the filter paper to provide a conductive polymer; and a gel of polytungustic acid provided on the polypyrrole film in the form of a cluster to provide a photo-catalytic property. The polypyrrole film may be vapor phase polymerized and coated onto a surface of the filter paper and the gel of polytungustic acid may be vapor phase coated onto the polypyrrole film in the form of a cluster. Thus, all electrode manufacturing steps can be carried out in the vapor phase so that manufacturing of such an electrode having a very large specific surface area is practical and large electrode areas may be manufactured.
