Abstract
A process for manufacturing an electrochemical cell comprising the steps of providing an electrode and applying electrolyte to the electrode using an ink-jet printer. In the preferred embodiment of the present invention, an ink-jet printing process is utilized to print the electrolyte onto the surface of the electrodes and separators or the electrode/separator bilayers. The ink-jet printing accurately meters and uniformly distributes the electrolyte throughout the pore structure of the separator and the electrode without contaminating the cell gasket. Preferably, a drop-on-demand ink-jet printing head is used to facilitate the electrolyte printing process. The ink-jet printing head is electronically pulsed to form and eject the electrolyte droplets from a nozzle of printing-head. The volume and the distribution of each electrolyte droplet are accurately determined and controlled by varying the pulse width and the pulse frequency of the printing head.
