本文采用模板辅助电沉积法从离子液体中制备了大孔铝电极。将聚苯乙烯（PS）球（直径600 nm）通过浸入含有PS球的醇悬浮液中施加到抛光的铜电极上。从氯铝酸盐离子液体[EMIm]Cl/AlCl 3（40/60摩尔%）沉积Al。在这个基板上。在化学溶解的PS球后，获得大孔铝电极，其作为主体材料用于从离子液体中沉积Li。在该基质中的锂沉积是可逆的，随着循环次数的增加显示出一定的活化。在Li沉积/溶解的10个循环之后，大孔结构仍然可见。(C)2010爱思唯尔有限公司版权所有。
In the present study macroporous aluminium electrodes were made by template assisted electrodeposition from ionic liquids. Polystyrene (PS) spheres (diameter 600 nm) were applied onto polished copper electrodes by immersion into an alcoholic suspension containing PS spheres. Al was deposited from the chloroaluminate ionic liquid [EMIm]Cl/AlCl3 (40/60 mol.%) on this substrate. After chemical dissolution of the PS spheres a macroporous aluminium electrode was obtained which served as a host material for Li deposition from ionic liquids. Lithium deposition in this matrix is reversible showing certain activation with an increasing number of cycles. After 10 cycles of Li deposition/dissolution the macroporous structure is still visible. (C) 2010 Elsevier B.V. All rights reserved.
