Abstract: NixCo1-xO for supercapacitors was prepared by combining co-precipitation and roasting,with NiSO4·6H2O and Co(NO3)2·6H2O as raw materials.The influences of Ni/Co molar ratio,precipitator and NH3·H2O additive on physical and electrochemical performances were studied through XRD,SEM and charge-discharge tests,etc.The results show that nano-materials are obtained under the conditions of NaOH as precipitators,n(NH3·H2O)∶n(NaOH)= 1∶10 and n(Ni)∶n(Co)=9∶1,the 200th specific capacity reaches 39.37 F/g,a...
