Method and apparatus for pressure filling an electrochemical cell

摘要

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.
