Abstract
A method of manufacturing a photo-rechargeable storage battery includes cutting a filter paper of glass fiber as a base material in a preselected shape to provide a cut filter paper; washing the cut filter paper; coating a polypyrrole film on at least a portion of a surface of the cut filter paper; and carrying a gel of poly-tungustic acid having a form of clusters on at least a portion of the glass fiber coated with the polypyrrole film thereby forming a composite electrode on the filter paper.
