Abstract

A method for making high power electrochemical capacitors (20) provides for depositing an electrically conducting polymer (24) onto a metal substrate (22). The electrically conducting polymer is initially grown in the presence of a soft anion, i.e., an anion having a high degree of polarizability. Subsequently, the polymer is treated with a relatively hard anion which at least partially replaces the soft anion in the polymer. The result is an electrochemical charge storage device which has enhanced electrochemical properties.
