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

那个电极，也就是那个更加需要电的电极被称为负极，而那个失去电的电极被称为正极。

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

电流频率测量——电波从正极到负极循环的次数。

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.

正常程，锂正极和负极之间传递能量。

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.

为了避免这种不利因素，帕洛阿尔托研究心计划两种材料构建负极：一种密集材料，以优化存储；另一种多孔材料，以加速电荷转移。

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，一个常见的碱性 AA 电池，锌金属与氢氧发生反应，转化为氧化锌，并从电池负极释放电。

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.

这个程是从细胞去极化开始的——也就是说，将细胞膜电位从负极推高到正极，超了触发电压门控通道打开的阈值。

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导联将右臂作为负极，左臂作为正极，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, 就会发现水的负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，负极部分越厚，移动穿越的速度就越慢。

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

干燥糊剂基质的程，大多数有机物挥发，只留下一个固体负极。

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。

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，所以它电负性更强，也就是我们的负极。

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。

Negative is going to be where the chlorine is.

负极处为氯气所处。

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程，即通外部的能量电重新回到负极由此电池得以再次放电。

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

这意味着锂从正极回到负极。
