铝空气电池(Aluminium–air battery)是从空气中的氧气与铝的反应产生电能。它们的能量密度有所有电池中最高的能量密度之一，但它们没有被广泛使用，因为有很高的阳极成本和当使用传统电解质时清除副产物的问题，这也限制了它们的用途主要是军事应用。但是，电动汽车用的铝电池具有比锂离子电池多达八倍里程范围的潜力，和显着较低的总重量。

铝空气电池是原电池; 即非可再充电电池。一旦铝阳极由它在浸在水基电解质的阴极与大气中的氧气反应而被消耗以形成水合氧化铝，电池将不再产生电力。然而，有可能用从回收的水合氧化铝制作新的铝阳极的机械方式对电池充电。如果铝空气电池被广泛采用，这样的回收将是必不可少的。

Aluminium–air batteries or Al–air batteries produce electricity from the reaction of oxygen in the air with aluminium. They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using traditional electrolytes and this has restricted their use to mainly military applications. However, an electric vehicle with aluminium batteries has the potential for up to eight times the range of a lithium-ion battery with a significantly lower total weight.
