There's an anode, which is the negative side of the battery.

一个阳，它电池负。

This means the lithium ions travel from the cathode back to the anode.

这意味着锂离子从正回到负。

The cathode acts as the battery's positive side, while the anode is the negative side.

正电池阳，而负电池阴。

However, the thicker the cathode, the slower the ions will move through it.

然而，负部分厚，离子移动速度就慢。

Electrical currents are measured in frequencies-the number of times a wave repeats a positive-to-negative cycle.

电流用频率测量——电从正到负循环次数。

The anode is made of graphite.

负石墨制成。

In the course of normal use, lithium ions shuttle energy between the cathode and anode.

在正常使用过程中，锂离子在正和负之间传递能量。

Both the cathode and anode can store lithium.

正和负都可以储存锂。

Making a battery that can store more energy requires a larger cathode containing more lithium ions.

制造能储存更多电量电池要求更大负以包含更多锂离子。

Copper likes having electrons more than zinc, so it's more electro negative and thus, our cathode.

铜和锌相比更加需要电子，所以它电负性更强，也就我们负。

Printing cathodes this way is just the beginning.

以这种方式打印电池负只一个开始。

Drying the substrate removes most of the organic material, leaving a solid cathode.

在干燥糊剂基质过程中，大多数有机物挥发，只留下一个固体负。

Recharging the battery just involves pushing those electrons back onto the negative electrode to reset the whole process.

对电池重新充电涉及到一个过程，即通过外部能量使电子重新回到负此电池得以再次放电。

The cathode of a typical electric car's battery would need tens of thousands of these interleaved fingers.

一个典型电动车电池负需要上万个这样交错指状物。

You know how the negative end of a magnet repels other negative magnets?

你知道磁铁负如何排斥其他负磁铁吗？

Lithium-ion batteries consist of four components: a cathode, an anode, a separator, and an electrolyte containing lithium ions.

锂离子电池四个主要部分组成：正、负、隔膜和含有锂离子电解液。

Different chemical reactions occur at the battery's positive and negative electrodes.

电池正和负会发生不同化学反应。

Reactions at the negative electrode release hydroxide ions (OH–).

负反应释放出氢氧根离子 (OH–)。

And so there's two different poles, a negative and a positive pole here.

所以这里有两个不同点，一个负和一个正。

The ECG machine uses the negative pole as zero reference.

心电图机使用负作为零参考。
