Study on electrochemical properties of the electrodes coated with the gradient functional oxide

The gradient method was applied for the first time to the making of electrode coatings. A series of experiments about the effects of the gradient method on the surface morphology and the electrochemical property of the gradient electrodes were conducted,including the composition and the changing times of the gradient electrode coatings,the coating number of every gradient composition,the heating temperature and the heating time for the first layer of the gradient electrode coatings,etc..The surface morphology,phase and electrochemical property were studied with the SEM,XRD and electrochemical property testing method.The experimental results indicated that the gradient method could reduce the cracks,improve the adhesive force and prolong the service life of the gradient coatings.
