On Preparation of Transition Metal Oxide Electrode Materials for Electrochemical Capacitors

In this paper, the preparation methods, research status of transition metal oxide (nitride) and its hydrous oxide applied to electrochemical capacitors (EC) in recent years are reviewed, and the pros and cons of these methods are also discussed. These methods can be classified into three kinds: liquids phase methods including sol-gel, thermal decomposition, and coprecipitation, gas phase methods including electrostatic spray deposition (ESD), chemical vapor deposition (CVD), and solid phase methods including low temperature solid phase and high energy ball milling.It is showed that the sol-gel is the most appropriate for the preparation of metal oxide electrode material for EC with Pseduocapacitance behaviors by comparison in principles, application fields of various methods mentioned above and electrochemical characteristics of the electrode materials prepared by these methods.
