PURPOSE:To obtain a cadmium electrode for a secondary battery which has an ecxellent capacity, left and the like by packing a slurry consisting of an active material and a solvent into a highly porous Ni-plate iron-fiber sintered body, and drying the body packed with the slurry so as to remove the solvent. CONSTITUTION:A slurry-like active material prepared by kneading an ethylene glycol solvent into mixture consisting of cadmium oxide and cadmium metal is packed into a sintered body, which has a porosity of above 90% and is prepared by sintering iron fibers with a diameter of 4-100mu before an Ni plating is performed. Next, the sintered body packed with the active material is subjected to partial drying in a dryer which is provided with an inflared-ray lamp or the like, and subjected to a given press work. Following that, it is dried at above 200 deg.C, which is the boiling point of the solvent, by means of a hot blast dryer or the like so as to remove the solvent completely. By the means mentioned above, the organic solvent is completely removed. Consequently, a cadmium electrode for a secondary battery which has no deteriorations and a good charge efficiency can be obtained. |
