摘要

In this paper, a hydrothermal synthesis method was applied to load Ni-Co Layered Double Hydroxide(LDH) directly on the Nickel foam (NF) as precursor, and by using an electrodeposition method togain the Co(OH) 2 /Ni-Co LDH composite. The structure and morphology of as-obtained composite wascharacterized by X-ray diffractometer (XRD) and scanning electron microscopy (SEM).Electrochemical performances of the as-obtained composite were tested by cyclic voltammetry andgalvanostatic charge-discharge techniques. The Co(OH) 2 /Ni-Co LDH composite, made by manyinterconnected nanosheets, was uniformly distributed. The as-obtained electrode achieved a capacity of825.6 F g -1 at 1 A g -1 .
