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.

正是池阳，而负是池。

Both the cathode and anode can store lithium.

正和负都可以储存锂。

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

流用频率测量——波从正到负循环次数。

Once all the electrons have reached the positive electrode, the battery is considered discharged, meaning it's out of power.

一旦所有子都流向正，池则放完毕，量耗尽。

At the positive electrode, the hydroxide ions get used up.

在正，氢氧根离子用完了。

The corresponding chest electrodes serve as the positive poles.

相应胸是正。

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

池正和负会发生不同化反应。

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 measurement of a voltage requires 2 poles: negative and positive.

负和正。

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

池两个主要部分是正和负，美国能源部阿贡国家实验室解释说。

Then, the electrons in part of the metal rod will be drawn towards the positive rod.

然后， 部分金属棒中子将被拉向正棒。

A battery is made of a positive electrode called a cathode and a negative electrode called an anode.

池由称为正和称为阳负组成。

And conventionally speaking, current flows from the positive to the negative terminal.

并且按照惯例，流流动 从正到负。

The negative side of the water molecules is attracted to the positive side of the sugar molecule and vice versa.

水分子负被吸引到糖分子正， 反之亦然。

But this means that electrons must flow from the negative terminal of the battery to the positive.

但这意味着子必须从 池负接正。

The electrons travel through, say, a light bulb, and then return to the battery at the positive terminal, where they're accepted by manganese dioxide.

子穿过灯泡之类用器，然后回到池正，被二氧化锰接收。

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，左臂作为正，形成一个指向右侧（左臂）向量。

The positive side of the molecule attracts electrons on adjacent molecules, while the negative side repels any electrons that are close to it.

分子正吸引相邻分子上子，而负排斥靠近它任何子。

But in an AC circuit, both the voltage and the current are constantly changing directions, from positive to negative and back again.

但是在交流路中，压和流都在不断地改变方向，从正到负，然后又回来。
