Compared with bare carbon sphere, the electrochemical performance of C@FexSy composite was significantly improved, with a high specific capacitance (267.45 F/g), good rate performance (201.08 F/g at 2.5 A/g), and superior cycling stability (almost no capacitance degradation after 1000 cycles). The results show that the obtained C@FexSy composite is a promising negative electrode material for supercapacitor %K Carbonaceous materials %K porous structure %K hydrothermal treatment %K electrochemical properties %K energy storage %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=309854
