By running an electrical current through the cell, using an ordinary battery charger, the copper in the anode (and in the pins) dissolves and is deposited on the leadcathode.
要想让电流通过电解池，你需要一个普通的电池充电器。阳极和针脚里的铜溶解之后会聚集在阴极上。

Because the cathode polarization effect more than a range, will lead to a large number of hydrogen, and separation coating becomes porous, rough, loose, scorched, even the powder, quality just drop.
