本发明公开了种超级电容器复合电极材料的制备方法，属于电容器电极材料的制备方法。其方法是以SnCl.nHO和RuCl.nHO为前驱体，纳米TiO为掺杂介质；通过湿法球磨工艺、细胞破碎超声法使纳米TiO高度分散于乙醇中形成悬浊液，将该悬浊液与SnCl.nHO、RuCl.nHO、去离子水混合，加入NHHCO溶液直到完全反应后静置7～8h，将沉淀物烧结后随炉冷却至室温，得纳米级SnO/RuO复合物，将该复合物、PVDF、碳黑按比例混合、研磨，滴加氮钾基吡吡烙烷酮配制成浆料，将该浆料涂刷在经等离子修饰基体上形成薄膜，真空干燥即得电极材料。本发明方法制备的复合电极材料具有比电容大、等效串联电阻小、稳定性、成本较低等特点；是种制备电容器电极材料的方法。 The invention discloses a preparation method of a composite electrode material for a super capacitor, and belongs to a preparation method of a capacitor electrode material. The method comprises the following steps: with SnCl .nH O and RuCl .nH O as precursors, and nano TiO as a doping medium, highly dispersing the nano TiO into ethanol to form a suspension liquid by a wet ball-milling technology and a cell-breaking ultrasonic method; mixing the suspension liquid, the SnCl .nH O, the RuCl .nH O and deionized water; adding an NH HCO solution until complete reaction, and then standing for 7-8 hours; sintering sediments and then cooling the sediments to a room temperature in a furnace to obtain
