METHODS OF MANUFACTURE OF ELECTRODES, SEPARATORS, AND ELECTROCHEMICAL ENERGY STORAGE DEVICES

摘要

A method of manufacture of an electrode having a non-uniform microstructure or mesostructure comprising: providing a first suspension containing a first electrode material and a second suspension containing a second electrode material; delivering the first and second suspension to a spraying means; operating the spraying means for a period of time to spray the first and second suspension on to a substrate located a distance from the spraying means; and controlling the mass flow rate of the first electrode material and/or the second electrode material to and/or through the spraying means as a function of time for at least a portion of the period of time.
