to their high theoretical cell voltage and energy density (8076 W·h/kg [5-8]. However, the main problem is that Al anodes passivate spontaneously when they are in contact with air or aqueous electrolytes [9... of Zn was added gradually and stirred using graphite rod for 3 min. After that a certain amount of pure Mg was also added gradually and stirred also for 3 min. The slag was removed before pouring......

Secondly, the AlCl3 powder was slowly added to a beaker filled with EC powder, and a glass rod was used to stir continuously until the powders...), elements O, Cl, W, and Ta were dispersed throughout the coating obtained by electrodeposition at -0.8 V (vs Al) and 323 K for 2 h. The XPS spectra of the electrodeposits are shown in Figs. 8(c......

. For example, the rod structure decreased; the flaky structure increased, the slab-like fragments increased; and varying degrees of stacking and agglomeration appeared. The kaolin desorbs the internal... in the experiment are shown in Figure 12. At low pressure (P/P0<0.8), the adsorption amount (W) slowly increases; however, a sharp increase occurs posterior to P/P0>0.8, with capillary condensation......
