PURPOSE:To manufacture a separator used for separating positive and negative electrodes of a redox-flow cell at low cost and to increase the energy density of the cell by specially treating a polymer substrate film. CONSTITUTION:Acylic acid which is anionic monomer and N, Ndimethylaminoacrylate quatenary methyl chloride which is cationic monomer are graft-polymerized to the same polymer substrate such as polyolefin film and fluorine-containing polymer film by electron beam irradiation. The film in which hydrophilic anion groups and cationic groups are formed on the same polymer substrate is manufactured at low cost. By using this film as the separator of a redox-flow cell, the energy efficiency of the cell is increased. |
