Influence　of　heat　treatment　temperature　on　the　phase　structures　and　capacitive　performance　of　the　Ti/RuO2　electrodes　was　conducted　by　X-ray　diffraction　(XRD),　galvanostatic　charge-discharge　test,　and　electrochemical　surface　analysis.　The　results　show　that　with　the　preparation　temperature　increases,　the　degree　of　crystallization　of　the　RuO2　coatings　gradually　improved,　and　the　capacitance　of　the　Ti/RuO2　electrodes　first　increased　and　then　decreased.　The　electrode　prepared　at　300°C,　around　critical　crystallization　temperature,　has　the　highest　specific　capacitance,　energy　density　and　power　density.
