Abstract
A method for the vibration filling of foam-structure or fiber-structure electrode plaques for galvanic cells, particularly for electrical accumulators, totally immerses one or more electrode plaques in a vibrating paste of active mass which has an active mass content of about 25 to 60 vol %, a maximum granulometry of the active particles of about 0.04 mm and in the unvibrated state a yield value of about 10 to 120 Pa and a plastic viscosity of about 0.1 to 1 Pas at 20.degree. C. The paste is preferably set in vibration with a frequency of about 40 to 125 Hz and an amplitude of about 0.1 to 1.5 mm by a vibration transmitter fitted inside the tank containing the paste.
