Abstract Sponge-like graphene oxide/carbon nanotubes (S-GO/CNT) composites were prepared by integrating GO nanosheets and CNT via non-template method. The as-prepared S-GO/CNT composites possess highly holey structure, leading to providing highly effective electrolyte pathway. Reduced S-GO/CNT (rS-GO/CNT) which can be used as electrode in supercapacitor can be prepared by annealing the S-GO/CNT composites without distinct deformation. The characterization of S-GO/CNT and rS-GO/CNT composites was investigated by X-ray diffractometer, transmission electron microscope and scanning electron microscope. The electrochemical measurements of rS-GO/CNT composites were performed by cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy. The rS-GO/CNT electrode possesses excellent rate capability and cycling stability owing to its high electrical conductivity and superior structural stability.
