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

这一点很关键，因为电池就是通过穿梭于它的阴极和阳极之间的离子来工作的。

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。

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

这是阴极和阳极之间的金属丝网，电子可以通过。

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

流行的阴极混合物使用镍、锰和钴的组合。

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

元素用于高品质电动汽车电池的阴极，以提高容量并减轻量。

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

电池由称为阴极的正极和称为阳极的负极组成。

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

变其电压使其排斥或吸引阴极发射的电子，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.

这种单向电流可以通过变阴极的电压来控制，这使得它释放更多或更少的电子。

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.

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

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

因为这种光最初是由负电极或阴极产生的，所以它被称为阴极射线， 它带有负电荷。

The Swedish company is adjusting in part to reduced demand for EVs, but it is also pausing its production of cathode active materials, essential elements for lithium-ion batteries.

这家瑞典公司正在部分调整以适应电动汽车需求的减少，但它也暂停了锂离子电池关键材料——阴极活性材料的生产。

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的阴极和阳极时，电子才能从一个半反应交叉到另一个半反应。

This element, made of thin aluminium sheets that sit atop the cathode and copper sheets that sit atop the anode, conducts electricity from the battery to the circuit.

元件由位于阴极顶部的薄铝片和位于阳极顶部的铜片制成，可将电流从电池传导到电路。

This combination of factors allows active materials such as lithium or graphite from the anode and cathode to seep into the current collectors and thereby improve their conductivity.

这些因素的结合使得阳极和阴极中的活性材料（例如锂或石墨）能够渗入集电器，从而提高其导电性。

Lightweight and reactive, it serves as an ideal cathode component; lithium-ion (Li-ion) batteries are widely used in electricity grids and can be found in most of the world's electric vehicles.

锂量轻、反应性好，是理想的阴极组件；锂离子(Li-ion)电池广泛应用于电网，世界上大多数电动汽车都使用锂离子电池。

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的显示技术，但最具影响力也是最早的是阴极射线管或 CRT。

As important as a cell's cathode, but much less studied, is the anode, the electrode where electrons reunite with their host atoms while a battery charges (during discharge, the electrons and ions reunite at the cathode).

阳极与电池的阴极一样要，但研究较少，阳极是电池充电时电子与其宿主原子新结合的电极（放电时，电子和离子在阴极新结合）。

All have had what it takes to serve as a cathode for a battery: namely, an ability to have electrons ripped away from their atoms to be turned into electric current, leaving positively charged ions behind.

所有这些元素都具备作为电池阴极的条件：即能够将电子从原子中剥离出来，转化为电流，留下带正电的离子。

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.

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

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的成分，这些成分是电池内部的正极（尽管最近发现的新储量减轻了这些担忧， 尤其是与钴有关的担忧）。
