Cobalt-nickel composite microspheres(CoNi-CM) with good dispersity and uniformity in size were synthesized by hydrothermal method using Ni(NO3)2·6H2O,Co(NO3)2·6H2O and CO(NH2)2 as precursors.The unique three-dimensional architecture greatly improved the faradaic redox reaction and electrolyte ions transfer.The results of electrochemical measurements in three-electrode configuration showed that CoNi-CM electrode exhibited the high specific capacitance,good rate performance and superior cycle stability.CoNi-CM was expected to be the optional electrode material for high performance supercapacitor.
