The effect of carbon nanotubes (CNTs) addition on the electrochemical performance of Al doped α-nickel hydroxide is studied. The microstructure and electrochemical performance of the prepared samples are characterized by XRD,SEM, electrochemical impedance spectroscopy, charge-discharge at different rate, and Charge-discharge cycling stability tests. The results show that the addition of CNTs could decrease the electrochemical reaction impedance dramatically, increase the specific discharge capacity at higher rate, and improve the Charge-discharge cycling stability reversibility.
