Solid oxide electrochemical cells (SOCs), elevated-temperature energy storage and conversion devices, are anticipated to play a pivotal role in future sustainable energy systems. Considerable research efforts have been devoted to this dynamic field, encompassing both lab-scale investigations and industrial exploration. However, a serious knowledge gap persists between laboratory development and industrial-scale application. One possible explanation is the large deviation that exists in the reported cell performances among different research groups. The errors introduced by complex experimental processes make it a significant challenge to distinguish the truly promising cell materials, fabrication techniques, and device systems. Thus, improving the reliability of cell performance obtained from laboratory-scale investigations is imperative. In this work, we begin by summarizing various parameters that can influence cell performance, including cell configurations, sealing materials and ways, current collection materials and techniques, current–voltage polarization test methods, and operation conditions. Then, their potential impacts on button cell performance are comprehensively reviewed and discussed. Finally, strategies to enhance the reliability of the cell performance are suggested. We believe that this specific article will offer valuable guidance for the future development of SOCs at the lab scale, while also furnishing meaningful information to promote industrial applications.

实验室规模固体氧化物单电池实验开发过程中的性能偏差分析和可靠性改进

固体氧化物电化学电池（SOC）、高温能量存储和转换装置预计将在未来的可持续能源系统中发挥关键作用。人们在这个充满活力的领域投入了大量的研究工作，包括实验室规模的研究和工业探索。然而，实验室开发和工业规模应用之间仍然存在严重的知识差距。一种可能的解释是不同研究小组报告的电池性能存在很大偏差。复杂的实验过程引入的误差使得区分真正有前途的电池材料、制造技术和设备系统成为一项重大挑战。因此，提高从实验室规模研究中获得的电池性能的可靠性势在必行。在这项工作中，我们首先总结了影响电池性能的各种参数，包括电池配置、密封材料和方式、集流材料和技术、电流-电压极化测试方法和操作条件。然后，全面回顾和讨论它们对纽扣电池性能的潜在影响。最后，提出了增强电池性能可靠性的策略。我们相信这篇具体文章将为实验室规模的 SOC 未来发展提供有价值的指导，同时也为促进工业应用提供有意义的信息。
