Abstract

Disclosed are a conducting polymer coated electrode of a metal oxide electrochemical pseudocapacitor having an improved performance and a method of manufacturing the same. The electrode includes a current collector and an active material coated on the current collector. The active material includes metal oxide and is coated with a conducting polymer on a surface thereof. Metal oxide electrochemical pseudocapacitor includes a plurality of electrodes described above, an electrolyte and a separator positioned between the electrodes to prevent a contact between the electrodes. The metal oxide pseudocapacitor including the electrode coated with the conducting polymer having a high electric conductivity, has an increased storing amount of electric energy and a decreased ESR to improve a high power performance.
