METHOD FOR FILLING BY VIBRATION ELECTRODE STRUCTURES OF THE FOAM OR FIBROUS TYPE FOR GALVANIC CELLS

摘要

A method is described for filling by vibration electrode structures of the foam or fibrous type for galvanic cells, in particular for electric batteries, in which one or more electrode structures are totally immersed in a vibrated active material paste which has an active material content of 25 to 60% by volume, a maximum active particle size of 0.04 mm and, in a non-vibrated state, a yield point of 10 to 120 Pa and a kinematic viscosity of 0.1 to 1 Pa . s at 20 DEG C. The paste is preferably vibrated by means of a vibration transmitter disposed within the paste container at a frequency of 40 to 125 Hz and with an amplitude of 0.1 to 1.5 mm.
