They have two electrodes, an anode and a cathode, that are connected by an electrically conductive material—generally a liquid—called an electrolyte.

蓄电池有阴阳两极，用导电材料——通常是一种叫做电解质的液体连接。

As well as lithium-iron phosphate, other innovative materials have been used for the three main battery components of anode, cathode and electrolyte.

与锂-铁磷酸盐一样，其他新型材料已经用到了电池的三个主要部件，阳极、阴极和电解液。

Conventional batteries, which typically use a liquid electrolyte, can suffer from undesirable chemical reactions that damage the battery's cathode.

典型的传统电池，使用的是电解液，会发生令人讨厌的化学反应，从而损坏电池的阴极。

They've tested the anode and the electrolyte, but they are still working on the final piece--the battery's cathode--using this same method.
