Abstract Reduced graphene oxide/carbon paper (rGO/CP) electrode was prepared by a new electrophoretic sedimentation combined with in situ reduction method. The rGO/CP electrode sheets were synthesized by covalent bond recombination in alkaline electrophoresis solution under ultrasonic dispersion, group dissociation and electric field force. SEM, FT-IR and Raman spectra showed that GO was loaded on carbon paper surface and reduced to rGO. The rGO/CP electrode prepared by reduction in the electrophoresis solution with conductivity of 12 mS·cm^-1 at 20 V for 10 min was studied in detail. Electrochemical results show that under current density of 0.05 mA·cm^-2, the first discharge capacity reached 4.161 mAh, which is 18.5 times of that of pure carbon paper electrode. With the cut-off capacity of 0.1 mAh and potential of 2.0—4.5 V, the rGO/CP electrode leaded to a decrease in charging potential by 0.19 V at the first turn, and presented much better cycle stability.
