A　CuCo2S4/graphene　composite　was　synthesized　using　a　simple　hydrothermal　method.　The　sample　was　characterized　by　field　emission　scanning　electron　microscopy,　transmission　electron　microscopy,　X-ray　diffraction,　nitrogen　adsorption　and　electrochemical　tests.　The　composite　had　a　hierarchical　porous　structure　with　micropores　of　0.7-1.2　nm,　mesopores　of　2-10　nm　and　a　total　poie　volume　of　0.1　cm(3).g(-1),　and　the　CuCo2S4　had　a　nano-belt　structure.　As　the　electrode　of　a　supercapacitor　the　composite　showed　a　high　specific　capacitance　of　665　F/g　at　7.5　mV/s,　and　excellent　rate　capability　and　cycling　stability..
