Abstract
Zinc electrodeposition was introduced on the surface of hydrogen absorbing alloy electrodes.The morphology and electrochemical properties of the electrodes were characterized by using scanning electronic microscope (SEM),cyclic voltammetry,electrochemical impedance spectroscopy (EIS) and galvanostatic charge-discharge tests.The results showed that after zinc electrodeposition,the electron transfer rate on the surface of the electrodes was accelerated and the contact resistance decreased,thus resulting in a polarization reduction of the electrodes.Furthermore,after zinc electrodeposition,the charge voltage of the batteries decreased,the discharge capacity at 1 C rate increased by 15.3% and the discharge plateau voltage increased 22 mV,the charge-discharge property was improved obviously.
