"The key is to use oxygen in the air as a re-agent, rather than carry the necessary chemicals around inside the battery," says Bruce.

“关键就在于使用空气中的氧气作为试剂，而不是在电池内部添装必需的化学成分。”布鲁斯说。

A lithium-air battery pulls oxygen from the air for its charge, so the device can be smaller and more lightweight.

锂空气电池从空气中吸收氧气充电，因此这种电池可以更小、更轻。

The oxygen, which will be drawn in through a surface of the battery exposed to air, reacts within the pores of the carbon to discharge the battery.

通过电池暴露在空气中的表面所吸入的氧气在碳孔中进行反应为电池放电。

Small flames were noted in one of the two incidents reported when gases escaping from the battery were ignited by an electrical short-circuit in the presence of ambient oxygen, but that was all external to the battery case.
