| Abstract: CoAl LDHs with different molar ratio of Ni have been prepared by chemical co-precipitation method.XRD results show that these materials have layered structures.Electrochemical tests show that Co(Ni)Al LDHs as electrode material have typical capacitive properties in a wide voltage range of 0.0 to 0.6 V;Co(Ni)Al LDH(Ni∶Co =4∶6)as an electrode material has the highest capacitance of 960F·g-1 and good cycling performance.But the poor capacitive properties of NiAl LDH electrode are showed in a narrow voltage range of 0.3 to 0.55 V. |
