A battery's electrolyte is the material through which ions (in this case lithium ions) pass from one electrode (the cathode) to another (the anode) inside a battery cell.
电池的电解质能让离子(此处为锂离子)自电池内部从一个电极(负极)传递到另一个(正极)。

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。

Researchers at Los Alamos National Laboratory have developed a platinum-free catalyst in the cathode of a hydrogen fuel cell that uses carbon, iron and cobalt.
