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——电波从正极到负极循环的次数。

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

然而，负极部分越厚，动穿越的速度就越慢。

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

一个是阳极，它是电池的负极。

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

正极是电池的阳极，而负极是电池的阴极。

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

在正使用过程中，锂在正极和负极之间传递能量。

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

制造能储存多电量的电池要求大的负极以包含多的锂。

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

铜和锌加需要电，所以它电负性强，也就是我们的负极。

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

这意味着锂从正极回到负极。

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，即通过外部的能量使电重新回到负极由此电池得以再次放电。

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，只留下一个固体负极。

The anode is made of graphite.

负极是由石墨制成的。

Both the cathode and anode can store lithium.

正极和负极都可以储存锂。

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

锂电池由四个主要部分组成：正极、负极、隔膜和含有锂的电解液。

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负极需要上万个这样交错的指状物。

Printing cathodes this way is just the beginning.

以这种方式打印电池负极只是一个开始。

This will require five pastes—two each for the cathode and the anode, plus a separator.

打印整节电池要求5种糊剂——制造正负极各需要两种，隔板一种。

The two main parts of a battery are the cathode and anode, the U.S. Department of Energy's Argonne National Laboratory explains.

电池的两个主要部分是正极和负极，美国能源部的阿贡国家实验室解释说。

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

你知道磁铁的负极是如何排斥其他负极磁铁的吗？

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

所以这里有两个不同的极点，一个负极和一个正极。

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

电池的正极和负极会发生不同的化学反应。
