Abstract

Solid oxide cells (SOCs) are high-temperature electrochemical energy conversion and storage devices, in which the interface and grain boundary are the most enigmatic areas. Rational construction of a high-quality interface/grain boundary is crucial for the promotion of mass transport, the increase of reaction sites, the decrease of technical costs for scale-up, and the improvement of operational stability, which remains the most intriguing challenge in the development of SOCs. In this review, we first provide a comprehensive analysis of the working mechanisms of interfaces and grain boundaries. This is followed by a discussion of optimization principles and a presentation of recent advances in interface/grain boundary engineering. Finally, we proposed perspectives that may lead to promising breakthroughs in the construction of a high-quality interface/grain boundary. This review is expected to be helpful for the scientific development and commercialization of SOCs integrated with renewable energy sources, as well as for other energy utilization research fields involving solid oxides.

界面和晶界工程，以更好的固体氧化物电池

固体氧化物电池（SOCs）是一种高温电化学能量转换和存储装置，其中界面和晶界是最神秘的区域。合理构建高质量的界面/晶界对于促进质量输运、增加反应位点、降低放大技术成本和提高运行稳定性至关重要，这是soc发展中最令人感兴趣的挑战。在本文中，我们首先对界面和晶界的工作机制进行了全面的分析。接下来是优化原理的讨论和界面/晶界工程的最新进展的介绍。最后，我们提出了可能导致高质量界面/晶界构建有希望突破的观点。本文的研究对可再生能源有机碳的科学开发和商业化以及其他涉及固体氧化物的能源利用研究领域具有一定的指导意义。
