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

阳极是石墨，阴极是镍、钴、锰和锂。

We refine them, so we get them into the form that we need for the production -- salts for nickel, cobalt and manganese, or hydroxides for lithium.

我们对它们进行精炼，将它们制成生产所需的形式——镍、钴和锰的盐，或锂的氢氧化物。

So batteries are made from minerals -- for example, nickel, cobalt and lithium -- and the way we approach this is going to determine how much we can further slash that carbon footprint.

因此，电池是由矿物质（例如镍、钴和锂）制成的，而我们处理这一问题的方式将决定我们可以在多大程度上进一步削减碳足迹。

A patch of Pacific Ocean seabed called the Clarion-Clipperton Zone (CCZ) is dotted with trillions of potato-sized lumps of nickel, cobalt, manganese and copper, all of which are of interest to battery-makers (see map).

太平洋海底的克拉里昂-克利珀顿区 (CCZ) 散布着数万亿个土豆大小的镍、钴、锰和铜块，所有这些都引起了电池制造商的兴趣（见地图）。
