然后给电池的正负电极施加电压。

A voltage is then applied across the cell electrodes.

回想先前的部分，锂离子电池包含一个使正负电极分离开来的薄板。

Recall from the previous section that lithium-ion cells contain aseparator sheet that keeps the positive and negative electrodes apart.

他们在塑料纤维中添加了一种称为“磷酸三苯酯”的组件以保持正负电极分离。

They added a component called "triphenyl phosphate" to the plastic fibers of the part that keeps negative and positive electrodes separate.
