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。

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和阳之间离子来工作。

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

正是电池阳，而负是电池。

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.

该元件由位于顶部薄铝片和位于阳顶部铜片成，可将电流从电池传导到电路。

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电动汽车需求减少，但它也暂停了锂离子电池关键材料——活性材料生产。

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，留下带正电离子。

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。

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和中活性材料（例如锂或石墨）能够渗入集电器，从而提高其导电性。

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).

阳与电池一样重要，但研究较少，阳是电池充电时电子与其宿主原子重新结合电（放电时，电子和离子在重新结合）。

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

这是一块位于和阳之间金属网筛，电子可以从中穿过。

He found that by replacing the titanium disulfide in the cathode with cobalt oxide.

他发现用钴酸锂替代中二硫化钛。

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

流行混合物使用镍、锰和钴组合。

Meanwhile, the electrons created at the cathode travel along the wires of the charging circuit towards the anode, where they reunite with the ions and are stored there.

同时， 产生电子沿着充电电路导线向阳移动，在那里与离子重新结合并储存在那里。

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，但最有影响力且也是最早出现是射线管，即CRTs。

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.

电子只能在我们通过导体将电池和阳连接起来时，从一个半反应转移到另一个半反应。

To protect people from this radiation, engineers mixed lead into the glass ray tubes— but this batch of GE televisions was produced with faulty tubes.

为了保护人们免受这种辐射危害，工程师们在玻璃射线管中混入了铅——但这一批通用电气公司电视机使用了有缺陷射线管。

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或产生，所以它被称为射线， 它带有负电荷。

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

电池由一个称为正和一个称为阳负组成。

It's the graphite from the anode, and it's the nickel, cobalt, manganese and lithium from the cathode.

它是来自阳石墨，以及来自镍、钴、锰和锂。

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，以提高容量并减轻重量。
