Three-dimensional nanostructured cobalt/nickel layered double hydroxides (Co1-xNix LDHs) were synthetized by a solvothermal method using ethanol as solvent and urea as alkali source. By simply tailoring the molar ratio of nickel and cobalt, the Co0.2Ni0.8 LDH with optimal electrochemical property is determined. Moreover, a hybrid device was successfully fabricated by using the Co0.2Ni0.8 LDH as the positive electrode and activated carbon (AC) as the negative electrode. The hybrid Co0.2Ni0.8 LDH//AC device delivered a high energy density and a power density, suggesting its promising energy storage applications in the future. (C) 2016 Elsevier B.V.
