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

这一点很关键，因为池就是通过穿梭于它极和阳极之间离来工作。

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

正极是池阳极，而负极是池极。

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

池由称为极正极和称为阳极负极组成。

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

流极混合物使镍、锰和钴组合。

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

这是极和阳极之间金属丝网，可以通过。

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

该元素于高品质动汽车池极，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.

改变其压使其排斥或吸引极发射，而实现快速流切换。

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

这种单向流可以通过改变极压来控制，这使得它释放更多或更少。

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极或极产生，所以它被称为极射线， 它带有负荷。

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池极和阳极时，才能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池极使锂钴氧化物，这是另一种分层材料，其池压可以达到4伏。

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.

该元件由位于极顶部薄铝片和位于阳极顶部铜片制成，可将流池传导到路。

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动汽车需求减少，但它也暂停了锂离池关键材料——极活性材料生产。

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.

这些因素结合使得阳极和极中活性材料（例如锂或石墨）能够渗入集器，而提高其导性。

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极射线管或 CRT。

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.

锂重量轻、反应性好，是理想极组件；锂离(Li-ion)池广泛应于网，世界上大多数动汽车都使锂离池。

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池极条件：即能够将原中剥离出来，转化为流，留下带正离。

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于制造极成分，这些成分是池内部正极（尽管最近发现新储量减轻了这些担忧， 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， 仍然可以让锂离来回流动。

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).

阳极与池极一样重要，但研究较少，阳极是池充时与其宿主原重新结合极（放时，和离在极重新结合）。
