Abstract
An electrochemical cell electrode such as the cathode element for a high energy density battery cell and its fabrication sequence are disclosed. Material such as finely-divided carbon particles is dispersed over the electrode surface during an ultrasonic energy assisted wet spraying process which produces very thin electrodes that are also low in fabrication cost and increased in uniformity and energy density capability. Fine particle material deposition on both a metal foil electrode and on an insulating member that is later joined to a metal foil electrode are contemplated.
