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.

作为阴极氢燃料调查的新型催化剂，它是由碳、铁以及钴三种原料组成。

Bacteria oxidize the organic matter and, in the process, produce electrons that run from the anode to the cathode within the fuel cell, creating an electrical current.

Many companies are working on coming up with better materials for the cathode or the anode in order to increase the energy density of the battery cell.
