In einem Schritt Ultraschall-beschichtetes Substrat zur Verwendung in einem Kondensator

摘要

A deposition process for coating a substrate with an ultrasonically generated aerosol spray of a pseudocapacitive material or a precursor thereof contacted to a substrate heated to a temperature to instantaneously solidify the pseudocapacitive material or convert the precursor to a solidified pseudocapacitive metal compound, is described. The ultrasonic aerosol droplets are much smaller in size than those produced by conventional processes and the heated substrate minimizes the possibility of contamination, thereby providing the present coating having an increased surface area. When the coated substrate is an electrode in a capacitor, a greater surface area results in an increased electrode capacitance.
