I can take you and immediately start designing batteries, because we need ions in motion, we need small ions in motion.
我可以从此让你快速起步设计电池，因为我们需要能运动的离子，我们需要能运动的小型离子。

It's all chemical processes. Second, pardon me, second is batteries.
这都是化学的过程，第二，不好意思，第二是电池。

see people with them, and what happens here is it's supposed to be those noise cancellation headphones. All they do is they take in the ambient noise that's around it, and there's actually battery in the headphones, that then produces waves that are going to destructively interfere with that ambient noise.
我从来没有用过这个,但你会看到有人带他们,它们可以作为消噪音耳机,它们所做的就是采入,周围的随机噪声，耳机里面是，有电池的，然后它能产生和,随机噪声相干相消的声波。

Because whenever I tell this story now, people start saying, " "Oh, well the evil machines are busy using your body as a battery" or whatever it was in the movie, right?
因为现在我一讲这个故事，人们就会说，“邪恶的机器忙着把你的身体当电池“,不管电影是怎样刻画的了？

Imagine how much power it takes to drive an artificial heart, so you've got to have a battery or some way of generating power continuously to operate that and that makes it difficult to think about implantable and so that's a really good example of Biomedical Engineering.
驱动人工心脏所需要的能量是难以想像的,所以需要电池或者是某种持续发电装置,来给人工心脏提供能量,这就增加了人工心脏的植入难度,这是很好的生物医学工程的例子

It comes from the fact that in an electrochemical cell, the cations are those that are reduced.
这来源于在电池中，正离子是被减少的。
-
So, this is what goes on in an electrolysis cell, and it works thanks to input energy from a power supply shown here.
所以，这是在一个电化学电池中发生的，它是靠输入的能量工作的,从和这个类似的电源输出的能量。

The only thing that stands between us and that is a suitable battery.
而之间唯一的困难则是,合适耐用的电池。
-
So, for example, in an electrochemical cell, it would be possible to take the sodium ion, give back its electron, and convert it into a metallic sodium, take the chloride ion, remove its electron, and restore chlorine gas.
所以，例如一个电化学的电池，它可能带有钠离子，让它得到电子，把它变成金属钠，得到氯离子，让它失去电子，作为氯气储存。
