PURPOSE:To obtain an economic electrode for a zinc-bromine battery which has long service life and with which good efficiency of a battery can be achieved by forming a synthetic resin layer containing a conductive powder and water-soluble polyvinyl alcohol, KCl or NaCl and then making this layer porous. CONSTITUTION:After a synthetic resin layer containing a conductive powder and water-soluble polyvinyl alcohol, KCl or NaCl is formed on the surface of a carbon plastic member, the thus obtained body is made porous to make a porous carbon plastic electrode. Carbon black powder, active carbon powder, graphite powder or a powder of a noble metal such as Pt or Ag can be used as the conductive powder. It is preferable that the surface of the carbon plastic member be coated by electrostatic spraying. The porosity of the electrode is produced by using hot water to elute the polyvinyl alcohol or the like contained in the synthetic resin layer thereby forming a porous irregular layer having holes. |
