The ever-rising demands for energy dense electrochemical storage systems have been driving interests in beyond Li-ion batteries such as those based on lithium and magnesium metals. These high energy density batteries suffer from several challenges, several of which stem from the flammability/volatility of the electrolytes and/or instability of the electrolytes with either the negative, positive electrode or both. Recently, hydride-based electrolytes have been paving the way towards overcoming these issues. Namely, highly performing solid-state electrolytes have been reported and several key challenges in multivalent batteries were overcome. In this review, the classes of hydride-based electrolytes reported for energy dense batteries are discussed. Future perspectives are presented to guide research directions in this field.
不断增长的对能量密集型电化学储能系统的需求推动了人们对超越锂离子电池的兴趣，例如基于锂和镁金属的电池。这些高能量密度电池面临着一些挑战，其中一些挑战源于电解质的可燃性/挥发性，或者电解质与负极、正极或两者都不稳定。最近，基于氢化物的电解质为克服这些问题铺平了道路。也就是说，已经报道了高性能的固态电解质，并克服了多价电池中的几个关键挑战。在这篇综述中，讨论了用于能量密集型电池的基于氢化物的电解质的类别。提出了未来的展望，以指导该领域的研究方向。
