A frequently undervalued aspect of lithium-ion battery performance reporting is the specification of the format and area of the tested cells. However, these parameters provide crucial insights into the quality of the electrodes used for cell assembly and the reliability of the data obtained from the investigated systems. Here we focus on the aspects of process standardization and industry collaboration necessary for translating nanoscale electrochemical processes to Ah-scale cells. We examine the role of cell area and format in promoting comparability and standardization in battery research studies with technology readiness levels of 4 or higher. In addition, we discuss the limitations, challenges and expectations associated with measuring and evaluating battery performance exclusively in small cell formats.
锂离子电池性能报告中一个经常被低估的方面是所测试电池的尺寸规格和面积。然而，这些参数能为用于电池组装的电极质量以及从所研究系统获得的数据的可靠性提供关键见解。在此，我们聚焦于将纳米级电化学过程转化为安时级电池所需的工艺标准化和行业协作方面。我们研究了电池面积和尺寸规格在技术就绪水平为4或更高的电池研究中促进可比性和标准化的作用。此外，我们讨论了仅以小尺寸电池形式测量和评估电池性能所涉及的局限性、挑战和期望。
