Lithium/air is a fascinating energy storage system. The effective exploitation of air as a battery electrode has been the long-time dream of the battery community. Air is, in principle, a no-cost material characterized by a very high specific capacity value. In the particular case of the lithium/air system, energy levels approaching that of gasoline have been postulated. It is then not surprising that, in the course of the last decade, great attention has been devoted to this battery by various top academic and industrial laboratories worldwide. This intense investigation, however, has soon highlighted a series of issues that prevent a rapid development of the Li/air electrochemical system. Although several breakthroughs have been achieved recently, the question on whether this battery will have an effective economic and societal impact remains. In this review, a critical evaluation of the progress achieved so far is made, together with an attempt to propose future R&D trends. A forecast on whether Li/air may have a role in the next years' battery technology is also postulated.
锂空气电池是一种引人入胜的储能系统。将空气有效地用作电池电极一直是电池界的长期梦想。空气在理论上是一种无成本材料，具有非常高的比容量值。在锂空气电池的特殊情况下，已经提出了接近汽油的能量水平。因此，在过去十年中，世界各地的许多顶尖学术和工业实验室都对这种电池给予了极大的关注。然而，这种强烈的研究很快就突出了一系列问题，这些问题阻碍了锂空气电化学系统的快速发展。尽管最近取得了一些突破，但这种电池是否会产生有效的经济和社会影响仍存在疑问。在这篇综述中，对迄今为止取得的进展进行了批判性评估，并试图提出未来的研发趋势。还对锂空气电池在未来几年的电池技术中是否可能发挥作用进行了预测。
