PURPOSE:To simplify the manufacturing process and shorten the manufacturing time of a plate for a battery, and realize a homogeneous high-density packing of an active material powder by introducing a base plate made of a foamy porous metallic body into a packing container which is packed with the active material powder, then giving vibrations to the base body so as to enable a sufficient amount of the active material powder to be packed into the holes of the base plate. CONSTITUTION:A base plate 1 is made of a foamy porous nickel body having a thickness of 1.8mm., a porosity of 96% and continuous holes with diameters of 100-500mu. The symbol 2 represents a packing container, which is packed with a mixture powder 3 consisting of 95 parts nickel hydroxide powder passed through a sieve of 200 mesh and 5 parts cobalt metal powder. A vibrator 4 installed at the bottom of the container 2 gives vibrations of 100Hz frequency and 1mm. amplitude for 30sec, to the base plate 1 which is positioned in the container 2. The volume of water 6 sprayed by a sprayer 6, should be 20vol% of the apparent volume of powder packed in the base plate 1. The particles of the packed powder are bound together by means of a polyethylene powder spreader 12 and a hot pressser 13. |
