与锂-铁磷酸盐一样，其他新型材料已经用到了电池的三个主要部件，阳极、阴极和电解液。

As well as lithium-iron phosphate, other innovative materials have been used for the three main battery components of anode, cathode and electrolyte.

与此同时，生产电瓶车车用蓄电池所使用的锂和钴等材料又大多从美国境外采购。

Meanwhile, materials such as lithium (PDF) and cobalt used in the manufacture of batteries for rechargeable vehicles are largely sourced outside the United States.

经由团队研究证实，将阳极和阴极结合在一起时，锂硫电池的续航力将是一般锂电池至少四倍之多，而且比现在的锂电池更为安全。

Together, the anode and cathode could yield a battery that lasts four times as long and is significantly safer than existing lithium-ion batteries.
