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

这一点很关键，因为电池就通过穿梭于它的阴极和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.

正极电池的极，而负极电池的阴极。

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

电池由称为阴极的正极和称为极的负极组成。

Tin is the preferred material for the anode in a lithium or sodium battery.

锡锂电池或钠电池的极材料。

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

这阴极和极之间的金属丝，电子可以通过。

Every single part of Surface Pro 9 is meticulously crafted with highest grade aluminum to achieve beautiful anodized colors.

Surface Pro 9 的每一个部件最高等级的铝合金材料打造的，以达到极氧化的颜色。

They're are the anode and cathode here.

它们这里的极和阴极。

That discovery enabled scientists to replace the reactive lithium anode with this safer material.

科学家利这一发现将电池中不稳定的锂极这种更安全的物质代替。

So far, graphite remains the best material available for anodes.

迄今为止，石墨仍然最好的极材料。

He worked for a famous annual called Anode.

他为一个叫" 极" 的著名年刊工作。

Researchers are developing anodes that use other materials.

研究人员正在开发使其他材料的极。

If the anode is at a slightly higher positive potential, the electrons are attracted to it, completing the circuit.

如果极处于稍高的正电位，电子就会被吸引到它上面，从而完成电路。

Recycled graphite, for instance, is not good enough to make new anodes—though it can be used for water filters.

例如，再生石墨不足以制造新的极——尽管它可以于滤水器。

The plan is to develop ways of making anode carbon from lignin, a natural polymer found in the cell walls of plants.

该计划开发利木质素制造极碳的方法，木质素一种存在于植物细胞壁中的天然聚合物。

Some soil-dwelling bacteria have evolved to deposit the electrons from glucose oxidation onto iron molecules, which allows researchers to trick them into living on the anode of a fuel cell.

一些土壤细菌将葡萄糖氧化过程所产生的电子安置在铁分子上，这样研究人员就可以诱使这些细菌存活在能量池的极上。

At the moment, most graphite for anodes is made in this way, but carmakers worried about their green credentials are expected, increasingly, to seek out the cleaner, mineral variety, says Andrew Miller of Benchmark.

目前， 大多数于极的石墨通过这种方式制造的， Benchmark 的安德鲁·米勒 (Andrew Miller) 表示，但越来越多的汽车制造商担心他们的绿色资质，他们将越来越多地寻找更清洁的矿物品种。

Graphite One is working with Sunrise New Energy, a Chinese anode-materials company in Zibo, Shandong province, on a purification system that would gently heat the graphite in the presence of recyclable cleaning gases.

Graphite One 正在与位于山东省淄博市的中国极材料公司 Sunrise New Energy 合作开发一种净化系统，该系统可以在存在可回收清洁气体的情况下温和加热石墨。
