That electrode, the one that wants the electrons more is called the cathode, and the one that gives up electrons is called the anode.

那个极，也就是那个更加需要子的极被极，而那个失去子的极被正极。

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

流用频率测量——波从正极到极循环的次数。

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

一个是阳极，它是的极。

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

正极是的阳极，而极是的阴极。

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

在正常使用过程，锂离子在正极和极之间传递能量。

PARC wants to evade this trade-off by constructing cathodes from two materials: one dense, and optimised for storage; the other porous, for the speedy transfer of charge.

了避免这种不利因素，帕洛阿尔托研究心计划使用两种材料构建极：一种使用密集材料，以优化存储；另一种使用多孔材料，以加速荷转移。

For example, in a typical alkaline double-A battery, zinc metal reacts with hydroxide ions, changing into zinc oxide and releasing electrons at the negative terminal.

例如，在一个常见的碱性 AA ，锌金属与氢氧离子发生反应，转化氧化锌，并从极释放子。

That process started by depolarizing the cell — that is, pushing the cell's membrane potential from negative toward positive, past a threshold that triggered voltage-gated ion channels to open.

这个过程是从细胞去极化开始的——也就是说，将细胞膜位从极推高到正极，超过了触发压门控离子通道打开的阈值。

Lead I uses the Right Arm as the negative pole and Left Arm as the positive pole, forming a vector that goes to the right.

I导联将右臂作极，左臂作正极，形成一个指向右侧（左臂）的向量。

If we look at the sodium we're going to have the negative parts of the water attracted to the positive parts of the sodium.

如果我们观察钠, 就会发现水的极部分被钠的正极部分所吸引。

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

然而，极部分越厚，离子移动穿越的速度就越慢。

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

在干燥糊剂基质的过程，大多数有机物挥发，只留下一个固体极。

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

锂离子由四个主要部分组成：正极、极、隔膜和含有锂离子的解液。

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子，所以它性更强，也就是我们的极。

The anode is made of graphite.

极是由石墨制成的。

Both the cathode and anode can store lithium.

正极和极都可以储存锂。

Negative is going to be where the chlorine is.

极处氯气所在处。

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

对重新充涉及到一个过程，即通过外部的能量使子重新回到极由此得以再次放。

Printing cathodes this way is just the beginning.

以这种方式打印极只是一个开始。

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

这意味着锂离子从正极回到极。
