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。

These thin bilayer films are layered onto both sides of a piece of ordinary paper, which serves as both the structural support of the battery as well as the electrode separator.

这些很薄的双层薄膜放在普通纸张的两面，纸张既是电池的支撑结构，同时也起到分离电极的作用。

Using a dedicated high-current electric circuit, like those installed for electric ovens, these can recharge the MINI E in 4.5 hours. (With an ordinary mains socket, by contrast, recharging could take all day.) For cars with smaller battery packs, like the Smart, overnight recharging from a conventional socket is possible.
