Abstract

The present invention provides a method for the preparation of printable electrodes, suitable for use in supercapacitors, and in particular for the application of an electrode composition to heat-sensitive substrates. The method of the invention incudes providing a substantially flat substrate; providing a flowable electrode composition comprising an aqueous electrolyte and a dry matter, wherein the dry matter content (DMC) of the flowable electrode composition ranges from about 25% to about 65% (w/w); placing a thin screen or a stencil having at least one opening over a top surface of the flat substrate; contacting a top surface of the screen or stencil with the flowable composition; removing the thin screen or stencil from the top surface of the substrate; and blotting the substrate and the electrode composition applied thereon under pressure of between about 5 to about 150 bar without heat (cold pressure), thereby obtaining a printed electrode having a DMC of between about 30% (w/w) to about 75% (w/w). The invention further provides printed electrodes, which can be prepared in a highly reproducible manner by the method of the invention.
