Abstract

Multicomponent systems were proposed in 2004 with tremendous potential in various applications. The central idea was to enhance the configurational contribution to entropy of a (nearly) equiatomic mixture of element to achieve invariability. In 2015, this concept of entropy induced stabilization was illustrated in a blend of oxides. Following this, other entropy stabilized oxides were studied, exploding in the vast composition space with materials showing enhanced properties. These systems were adept in wide range of technologies ranging from thermal barrier coatings, ultra-high temperature refractories, wear and corrosion resistant coatings, catalysts, thermoelectrics, and electrochemical energy storage systems (EES). We will walk through the recent developments in high entropy oxides for reversible energy storage in this review, looking at the high entropy attributes that enhance their electrochemical capabilities. The influence of entropy can no longer be avoided in ceramics and will be crucial to the advancement of sustainable technologies in the future.
用于可逆锂离子电池的高熵氧化物:简评
多组分系统于 2004 年提出,在各种应用领域具有巨大潜力。其核心思想是增强(近似)等原子元素混合物的构型对熵的贡献,以实现不变性。2015 年,这种熵诱导稳定的概念在一种氧化物混合物中得到了说明。此后,又对其他熵稳定氧化物进行了研究,在广阔的成分空间中,材料显示出更强的特性。这些系统适用于各种技术,包括热障涂层、超高温耐火材料、耐磨和耐腐蚀涂层、催化剂、热电和电化学储能系统(EES)。在本综述中,我们将介绍用于可逆储能的高熵氧化物的最新发展情况,探讨可增强其电化学能力的高熵属性。熵的影响在陶瓷中已无法回避,它对未来可持续技术的发展至关重要。
