That matters because a battery works by shuttling ions between its anode and its cathode.

一点很关键，因为电池就是通过穿梭于它阴极和阳极之间离子来工作。

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

正极是电池阳极，而负极是电池阴极。

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

电池由称为阴极正极和称为阳极负极成。

Popular cathode blends use combinations of nickel, manganese and cobalt.

流行阴极混物使用镍、锰和钴。

This is a wire screen between the cathode and anode through which electrons could pass.

是阴极和阳极之间金属丝网，电子可以通过。

The element is used in the cathodes of high-quality electric-car batteries to boost capacity and cut weight.

该元素用于高品质电动汽车电池阴极，以提高容量并减轻重量。

Varying its voltage makes it either repel or attract the electrons emitted by the cathode, thus, enabling fast current-switching.

改变其电压使其排斥或吸引阴极发射电子，从而实现快速电流切换。

This unidirectional current flow could be controlled by varying the voltage to the cathode, which makes it release more or less electrons.

种单向电流可以通过改变阴极电压来控制，使得它释放更多或更少电子。

Because this light was originally produced by a negative electrode, or cathode, it was called a cathode ray, and it had a negative charge.

因为种光最初是由负电极或阴极产生，所以它被称为阴极射线， 它带有负电荷。

Electrons can then cross from one half reaction to the other, only when we connect the cathode and the anode of the battery via conductors.

只有当我们通过导体连接电池阴极和阳极时，电子才能从一个半反应交叉到另一个半反应。

His group at Oxford University demonstrated that a battery using a cathode made from lithium cobalt oxide, another layered material, could produce as much as 4 V.

他在牛津大学团队证明电池阴极使用锂钴氧化物，是另一种分层材料，其电池电压可以达到4伏。

INTRO A lot of different display technologies have been created over the decades, but the most influential, and also the earliest, were Cathode Ray Tubes, or CRTs.

简介 几十年来出现了许多不同显示技术，但最具影响力也是最早是阴极射线管或 CRT。

They also worry about cobalt and other ingredients used to make cathodes, the positive electrodes inside those batteries (though recent discoveries of new reserves have dampened those concerns as they relate to cobalt in particular).

他们还担心钴和其他用于制造阴极成分，些成分是电池内部正极（尽管最近发现新储量减轻了些担忧， 尤其是与钴有关担忧）。

Its cathode is made from a lithium metal oxide and its anode is made of graphite, and they’re kept apart by a thin polymer separator that still lets lithium ions flow back and forth.

它阴极由锂金属氧化物制成， 阳极由石墨制成，它们由薄聚物隔板隔开， 仍然可以让锂离子来回流动。
