In this paper, by analyzing the electroosmosis of aqueous solution and the experiment of aluminum electrolysis, it is confirmed that electro-osmosis exists in aluminum electrolysis. The formula of electroosmosis velocity is deduced by theoretical calculation. In the experiment, the effect of current density on electroosmosis was analyzed by changing the current density. As the current density increased, the depth of electroosmosis increased. The existence of electroosmosis was further confirmed by X-ray diffraction and electron probe analysis. The infiltrated material and the depth of penetration were analyzed.
