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)。

When the battery is being charged, positively charged lithium ions break away from the cathode and travel in the electrolyte to the anode, where they meet electrons brought there by a charging device.

电池充电时，从负极分离的锂离子经过电解质运动到正极，并和由充电装置提供的电子相遇。

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。

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.
