ABSTRACT:
A process for the production of prismatic alkaline accumulator cells of rectangular cross-section, wherein firstly an electrode unit comprising positive and negative electrodes with interposed separators and a cover of plastic material is produced. The cover has a feed through arrangement and connecting contacts for the electrodes. After the casing of the plastic material is filled with a measured amount of electrolyte, the electrode unit is lowered step wise and with pauses into the casing in such a way that the dry electrode pack can become fully impregnated by absorption without electrolyte issuing from the casing. When the cover is then fitted on the casing, the two parts are welded together to afford absolute sealing integrity. In order to reduce possible, even high increased pressure due to improper handling the cover contains a shaped recess, a rubber pin that covers over a bore in the cover leading into the interior of the casing, and a plastic ball that is pressed into the recess in the cover and fixes the rubber pin in place. In the event of a slightly increased pressure, the rubber pin first lifts off the bore and allows gas to escape to the exterior. In the event of a very high and sudden increase in pressure, the rubber pin and the ball are thrown out.
