The invention discloses a novel supercapacitor carbon nano onion conductive agent slurry and a supercapacitor thereof. The carbon nano onion slurry comprises, by weight ratio, 0.01-10% of carbon nanoonions, 90-100% of a solvent and 0.01-10% of a dispersing agent, wherein the average particle diameter of the carbon nano onions is 20 nm. According to the novel supercapacitor carbon nano onion conductive agent slurry and the supercapacitor, the carbon nano onions are applied to a supercapacitor conductive agent, and the extremely low additive amount can increase the specific capacity of the supercapacitor and can maintain good cycle stability. 本发明公开了一种新型超级电容器碳纳米洋葱导电剂浆料及其超级电容器。其中碳纳米洋葱浆料，按重量配比，包括碳纳米洋葱0.01～10％，溶剂90～100％和分散剂0.01～10％；所述碳纳米洋葱平均粒径为20nm。本发明将碳纳米洋葱应用于超级电容器导电剂中，极低的添加量既可提升超级电容器的比容量，同时又可保持良好的循环稳定性。
