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 lead cathode.
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。

It and reversing current different is not to be, but with a anode intermittently stop, because the intermittent power supply current interrupted, cathode potential with time periodically change.
