摘要

与最先进的锂离子电池相比，锂金属电池的能量密度要高得多。然而，锂枝晶生长所带来的安全隐患严重阻碍了它们的商业化。2018 年，在锂金属负极中发现了一种新的锂氢化物（LiH）枝晶，引起了广泛关注和激烈讨论。关于锂氢化物的位置、形态、含量、形成机制以及对电池性能影响的研究产生了各种不同的结果，有时甚至是相互矛盾的结果。本综述总结了锂氢研究的最新进展，讨论了目前存在的争议，并概述了该领域的未来前景。

Understanding Lithium Hydride in Lithium Metal Batteries: Advances, Controversies, and Perspectives

Lithium metal batteries exhibit significantly higher energy densities compared to state-of-the-art lithium-ion batteries. However, their commercialization is critically impeded by safety hazards arising from lithium dendrite growth. In 2018, a new dendrite of lithium hydride (LiH) was identified within the lithium metal anode, garnering widespread attention and inciting intense debate. Research on the location, morphology, content, formation mechanisms, and effects of LiH on battery performance has yielded diverse and sometimes conflicting results. This review summarizes the latest advancements in LiH research, discusses the prevailing controversies, and outlines future perspectives in the field.

期刊介绍： Energy & Fuels publishes reports of research in the technical area defined by the intersection of the disciplines of chemistry and chemical engineering and the application domain of non-nuclear energy and fuels. This includes research directed at the formation of, exploration for, and production of fossil fuels and biomass; the properties and structure or molecular composition of both raw fuels and refined products; the chemistry involved in the processing and utilization of fuels; fuel cells and their applications; and the analytical and instrumental techniques used in investigations of the foregoing areas.
