PURPOSE:To increase the content of electrolyte and improve quick discharge characteristics by mixing a conduction agent powder and a viscosity improver capable of being gasified at a temperature equal to or lower than a specified melting point, into a hydrogen occluded alloy powder, forming the resulting mass under pressure together with a current collection plate, and burning the resulting plate. CONSTITUTION:A hydrogen storage alloy powder, a conductor powder, a resinous binder powder, and a viscosity improver capable of being gasified at a temperature equal to or lower than the melting point the binder resin are mixed together. The mixed powder is formed under pressure together with a current collection plate and the formed plate is rolled. Then, the resulting plate is burned at a temperature equal to or higher than the melting point of the binder resin. Then, the binder resin powder particles are melted and bound together to form a three-dimensional net-like structure, thereby binding the alloy powder particles and retaining them. On the other hand, since the binder resin powder particles included in the formed plate are gasified, a large number of pores are produced. Therefore, a hydrogen storage electrode having an increased porosity is obtained and hence the content of the electrolyte impregnated therein is increased to improve the quick discharge characteristics. |
