AN ELECTROACTIVE FILM ON A SUBSTRATE AND METHOD OF MAKING

摘要

The electroactive product of the present invention is a metal cyanide film on a substrate, wherein the improvement is the metal cyanide film having a flux throughput capacity greater than 0.54 millicoulombs/second-cm2 as measured by the specific cyclic voltammetry procedure. The improved metal cyanide film generally has a flux throughput capacity greater than that of unimproved metal cyanide film wherein the improved metal cyanide film was deposited at a slow rate. The present invention enjoys the advantages of greater cation equivalent loading capacity, and achieving ion separations using half the amount of electricity as other electrochemical ion separations.
