High-entropy materials (HEMs) hold promise for a variety of applications because their properties can be readily tailored by selecting specific elements and altering stoichiometry. In this Perspective, we highlight the emerging potential of HEMs in energy and electronic applications. We place particular emphasis on (ionic and covalent) ceramics that have only emerged in powder form since 2015. Although the discovery of opportunities is in its early stages, we discuss a few case studies in which the use of HEMs has led to improved material properties and device performance. We also correlate features with the respective properties and identify topics and effects for future investigations. An overview of these intrinsic properties, such as cocktail effects, lattice distortions and compositional freedom, as well as a list of general attributes, is given and linked to changes in material characteristics.

高熵材料 (HEM) 具有多种应用前景，因为它们的特性可以通过选择特定元素和改变化学计量来轻松定制。在本视角中，我们强调了 HEM 在能源和电子应用中的新兴潜力。我们特别关注自 2015 年以来仅以粉末形式出现的（离子和共价）陶瓷。尽管机会的发现还处于早期阶段，但我们讨论了一些案例研究，其中使用 HEM 改善了材料性能和设备性能。我们还将特征与各自的属性相关联，并确定未来研究的主题和效果。给出了这些固有属性的概述，例如鸡尾酒效应、晶格畸变和成分自由度，以及一般属性列表，并将其与材料特性的变化联系起来。
