Abstract

The CoOOH film on the nickel foil is fabricated via layered hydroxide cobalt acetate (LHCA) film with nanosheets morphology, which is synthesized by chemical bath deposition method. The LHCA nanosheets film is converted into CoOOH fine nanoflake films with high porous and high surface area by the oxidation reaction based on the dissolved oxygen in KOH solution. The intercalated acetate into the LHCA layer, which is strong basic species, caused the oxidation. The electrochemical capacitance property of the resultant CoOOH fine nanoflake film is studied by cyclic voltammetry (CV). In the CV, a good high rate property is indicated by the results of CV at high rate scan. It is caused by the specific morphology of the CoOOH fine nanoflake films.
