镁硫（Mg-S）电池由于其高理论容量和低活性材料成本在过去十年中得到了研究。然而，为了实现镁硫电池的实用化，仍有几个关键问题尚未克服。在本视角中，讨论了镁硫电池与锂电池相比性能较差的原因。本视角强调了多硫化镁的独特性质以及由此产生的镁阳极钝化问题，以促进镁硫电池研究的进展。
The magnesium–sulfur (Mg-S) battery has been investigated in the past decade due to its high theoretical capacity and low active material cost. However, there are still several key issues that have not been overcome to enable practical Mg-S batteries. In this Perspective, the reasons for the poor performance of the Mg-S battery compared to its Li counterpart are discussed. The unique properties of magnesium polysulfides and the resulting passivation problem of the Mg anode are emphasized in this Perspective to facilitate progress in Mg-S battery research.
