An electrochemical cell, carried along a cell production line, is filled with liquid electrolyte under pressure. First, the electrolyte is dispersed on top of the cell electrode assembly within an open ended cell casing. Then a pressurizing chamber is mated with the cell support member of the conveyor mechanism so as to form a pressurizing volume surrounding the cell, whereupon a gas under pressure is introduced into the chamber and forces the electrolyte into the separator of the electrolyte assembly for rapid and complete absorption of the electrolyte.

Method and apparatus for pressure filling an electrochemical cell

An apparatus for applying and affixing sleeves of dielectric plastic material to galvanic cells. The apparatus includes a carrousel having a cell receiving station, a sleeving station and a discharge station with a tester for testing and rejecting cells between the receiving and sleeving stations. The apparatus further includes feeding means for feeding sleeve length units from a spool supply, gripping means for gripping each fed length, while such length is cut and for opening the cut length, pusher means for pushing the cut length from the gripper onto the cell and heater means for heating and shrinking the cut length on the cell into gripping contact with such cell.
