Abstract

Due to global shifts in energy consumption and increasing demand for efficient, safe, and cost‒effective energy storage solutions, high-entropy materials (HEMs) have garnered great attention. The HEMs, composed of five or more elements in near‒equimolar ratios, exhibit unique properties such as high entropy effects, lattice distortion, sluggish diffusion kinetics, and the "cocktail" effect. These characteristics of HEMs significantly enhance the performance of rechargeable batteries and supercapacitors by improving electronic conductivity and ionic transport of the relevant battery composition as well as expanding the operational battery temperature. This paper timely summarizes the function principles of the four primary enhancement mechanisms of HEMs and resultant recent applications in energy storage and conversion technologies, including cathodes, anodes, and electrolytes. Considerable emphasis is focused on the functional orientation screen and the synthesis of HEM elements/structures towards stability and power capability of the electrode reactions. Finally, the current challenge, the possible solving strategies and the future research trend for HEMs are outlined. It is believed that this review will offer timely and comprehensive information on the future research directions of HEMs to boost high‒performance energy storage communities.

用于高质量能量存储和转换的先进高熵材料

由于全球能源消费的变化以及对高效、安全、经济的能源存储解决方案的需求不断增加，高熵材料（HEMs）受到了极大的关注。由五种或更多元素以接近等摩尔的比例组成的hem表现出独特的性质，如高熵效应、晶格畸变、缓慢的扩散动力学和“鸡尾酒”效应。HEMs的这些特性通过改善相关电池成分的电子导电性和离子输运以及提高电池的工作温度，显著提高了可充电电池和超级电容器的性能。本文及时总结了四种主要增强机制的功能原理及其在能量存储和转换技术中的最新应用，包括阴极、阳极和电解质。相当多的重点放在功能取向筛选和HEM元素/结构的合成上，以提高电极反应的稳定性和功率能力。最后，对当前的挑战、可能的解决策略和未来的研究趋势进行了概述。相信本文的综述将为HEMs未来的研究方向提供及时、全面的信息，推动高性能储能领域的发展。
