A　series　of　nominal　composition　Ti/(ZrO2)(x)(RuO2)(1-x)　(0.1　＜=　x　＜=　0.9)　coatings　changed　in　10%　steps　was　deposited　on　titanium　substrate　from　RuCl3　center　dot　nH(2)O　and　ZrCl4　containing　ethanol　solution　by　thermal　decomposition　method.　The　X-ray　diffraction　(XRD),　high-resolution　transmission　electron　microscopy　(HR-TEM)　and　electrochemical　tests　were　performed　to　clarify　the　effects　of　ZrO2　content　on　the　structure　and　capacitive　property　of　Ti/(ZrO2)(x)(RuO2)(1-x).　The　results　show　that　by　adding　ZrO2　into　the　coatings　the　degree　of　crystallization　of　RuO2　decreases.　The　specific　capacitance　firstly　increases　and　then　deceases　with　the　increase　of　ZrO2　content　in　the　mixed　oxide　coatings.　The　film　of　Ti/(ZrO2)(0.6)(RuO2)(0.4)　consisting　of　amorphous　matrix　and　fine　nano-crystalline　RuO2　(about　4　nm)　has　the　maximum　specific　capacitance　of　713.27　F/g(RuO2).
