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

一个是阳，它是电池的。

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

这意味着锂离子从回。

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

是电池的阳，而是电池的阴。

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

然而，部分越厚，离子移动穿越的速度就越慢。

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——电从循环的次数。

The anode is made of graphite.

是由石墨制成的。

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

在常使用过程中，锂离子在之间传递能量。

Both the cathode and anode can store lithium.

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的电池要求更大的以包含更多的锂离子。

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

铜锌相比更加需要电子，所以它电性更强，也就是我们的。

Printing cathodes this way is just the beginning.

以这种方式打印电池只是一个开始。

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

在干燥糊剂基质的过程中，大多数有机物挥发，只留下一个固体。

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一个过程，即通过外部的能量使电子重新回由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.

一个典型的电动车电池的需要上万个这样交错的指状物。

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

你知道磁铁的是如何排斥其他磁铁的吗？

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

锂离子电池由四个主要部分组成：、、隔膜含有锂离子的电解液。

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

电池的会发生不同的化学反应。

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

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的点，一个一个。

The ECG machine uses the negative pole as zero reference.

心电图机使用作为零参考。
